Question set 1: One instructor believes that students take more than 2 classes per quarter on average. He randomly interviewed a
Sveta_85 [38]

Answer:

There is statistical evidence at 95% level to claim that students attend more than 2 classes per quarter

Step-by-step explanation:

Given that one instructor believes that students take more than 2 classes per quarter on average. Let X be the no of classes students take.

H_0: \bar x =2\\H_a: \bar x >2

(Right tailed test at 5% significance level)

\bar x =2,3 \\s = 0.8

Mean difference = 2.3-2=0.3

Std error = \frac{0.8}{\sqrt{24} } \\=0.1633

Test statistic t = mean diff/std error = 1.84

p value =0.039

Since p <0.05, we reject null hypothesis.

There is statistical evidence at 95% level to claim that students attend more than 2 classes per quarter

How do you multiply a percentage and a whole no.
const2013 [10]
First, change the percentage to a decimal, by moving the decimal point to the right twice (from the farthest left).

Then multiply the numbers together.


finally, if you need it as a percentage, move the decimal point to the left two decimal places, and you get your percentage again (round if necessary)

hope this helps
