An educational psychologist wants to test whether a new teaching method positively affects reading comprehension scores using a significance level of 0.01. The mean reading comprehension scores of students using the old method has a value of 34 . Assume scores in the population are distributed normally. State the Null and Alternative Hypotheses.

Null hypothesis

H0 : μ = 34

Alternative hypothesis

H1 : μ ≠34

Step-by-step explanation:

Given data The mean reading comprehension scores of students using the old method has a value of 34

The population mean μ = 34

Null hypothesis :-H0

The hypothesis that specifies a default course of action unless contradicted

by data.

Alternative hypothesis(H1)

A hypothesis that contradicts the assertion of the null hypothesis

Null hypothesis

H0 : μ = 34

Alternative hypothesis

H1 : μ ≠34

the answer is 45 i just did it on oddesy ware

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
