Dreaming can be a boss

"I didn't! Don't talk nonsense!" Ning Shiyuan's face became redder, and she reached out to poke Su Lu, but Su Lu grabbed her wrist, and she quickly stretched out the other hand, and the result He was still caught by Su Lu quickly, without even touching the corner of Su Lu's clothes.

With stronger reaction and stronger strength, Su Lu is now comparable to a professional athlete who has been professionally trained for several years. In his eyes, Ning Shiyuan's movements are like a kitten catching butterflies. She is so cute and silly. , very cute.

"let me go!"

"Don't let it go!"

Su Lu grabbed the girl's wrist, and the delicate and smooth skin made him feel a different sense of touch - it must be much better than when he was pulling with his best friend in the dormitory, the feeling of grabbing the wrist of a big guy who picks feet.

"Quickly let it go! Otherwise, when Professor Zhang comes in, I'll say you're bullying me!"

"Then I won't let you go." Su Lu laughed.

…………

The three people observing the situation couldn't bear to look directly.

Looking at it further, their 24k titanium alloy single dog eyes were blinded by a flash.

"Beast, oh beast!"

"Look at the girls in our class, all of them look strange."

"Hey, our face value representative of 232 is going to betray the bachelor revolution!"

Chapter 43 class

The class bell rang, and Professor Zhang walked into the classroom.

He looked around, and suddenly noticed two familiar faces, and saw Su Lu and Ning Shiyuan talking there.

Professor Zhang's eyes became strange, Su Lu was fine with it, but Ning Shiyuan, a doctoral student, came over to take a basic class, which made him a little confused.

The relationship between his two students seems to be developing in a wrong place.

But he didn't care about these things, looked at the others again, and said with a smile: "Hello, classmates, I haven't seen you for a summer vacation, and everyone has gained a lot of weight. Do you stay at home every day and don't go out to exercise?"

The whole class burst into laughter, and a girl shouted: "No way, I've lost weight!"

"Teacher, you actually monitored me!"

……

Laughter even worse.

Professor Zhang said with a smile: "Then did you have a preview when you stayed at home?"

As soon as these words came out, the chatter was dead, and the voice in the classroom became quieter.

Anticipating this situation, Professor Zhang snorted softly, then opened the book, and said while flipping through the book, "You guys, econometrics is very difficult. The rate of failing exams over the years has been very high. You don't study hard. , then don’t ask me to beg for mercy.”

The students looked terrified.

Su Lu and Ning Shiyuan, who were sitting in the back row, were also listening. When they heard Professor Zhang scaring the students, Ning Shiyuan smiled, and then said to Su Lu: "If you meet someone who doesn't know how to do it, come to me, I will give you Tuition!"

Su Lu: "Is it free?"

Ning Shiyuan pushed him lightly, rolled her eyes and said, "Is there still a fee? My sister is so kind to you, why would you ask for money?"

Su Lu chuckled, but he didn't say that he didn't use it for class at all.

He even decided to come to every class in the future. As for why, it is self-evident.

"That's good, do you want to make an appointment in the library on weekends? It just happened that Professor Zhang asked me to study mathematics hard so that I can develop financially in the future. My sister will teach me when the time comes."

Of course Ning Shiyuan agreed.

"no problem!"

Su Lu smiled lightly, then looked towards the podium, only to see that Professor Zhang started writing questions on the blackboard after a disagreement.

“用一组有20个观测值的样本估计模型yi=β0+β1xi+μi 后，在01的显著性水平下对β1的显著性作t检验，则β1显著地不等于零的条件是t统计量绝对值大于（？）。”

After writing this question, Professor Zhang turned his head to look at the stunned students, and said with a smile: "Come on, let's take a simple question to test everyone, and check everyone's preview situation."

There are quite a few top students in the class, as can be seen from the fact that Su Lu's GPA of 36 and above is also ranked in the top ten, but the top students who have put aside mathematics for half a year can only look at this with a confused face. formula.

What is μ?absurd?Meow?

Does β read beta?

Does Beta fly a plane or a tank?

e...

Far away.

There are still some masters who are previewing. At this time, they are frantically flipping through the book, recalling which knowledge point this question should be about. It seems to be a regression analysis?Or the regression equation?

"Tuigui, Lao Zhang is trying to show us off!"

"I heard that econometrics is one of the subjects with the highest failure rate in universities..."

"Try it, Baidu Econometrics, and there is a 'everyone is still searching' below, you go and see what the first one is."

Someone curiously searched and tried it, and then said dumbfoundingly: "God, 'Econometrics is so fucking difficult', it's over, I'm bad at math, cool!"

Unlike other people racking their brains, Su Lu in the corner just glanced at it, calculated in his mind for two seconds, and finally came up with the answer.

His mental arithmetic ability at this time is far superior to that of the past, perhaps not as good as those bigwigs who specialize in practicing this skill, but it is also far superior to ordinary people. In addition, this problem is really simple, so naturally it does not take much time.

He lowered his head uninterestedly, and turned over the textbook in his hand. He had already memorized the content on it backwards, and almost completely understood it, but it just consumed some mental energy.

Every time he turned a page, he could speak out the knowledge points on it directly, word for word.

Seeing him like this, Ning Shiyuan asked, "Did you make it?"

Su Lu gave a soft "hmm".

"Then tell me what the answer is." Ning Shiyuan's eyes flashed with splendor.

Su Lu glanced at her, did he want to test him?Turning his eyes, he smiled and said, "Is there any reward for making it?"

"How about I invite you to dinner at noon?"

"can."

Su Lu immediately took out his pen and found a place to write the answer.
