An educational psychologist wants to test whether a new teaching method makes a difference to 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 46.3 . Assume scores in the population are distributed normally. State the Null and Alternative Hypotheses.

H' : u = 46.3,

H1: u > 46.3

H1: u < 46.3

H1: u ≠ 46.3

Step-by-step explanation: Let H' represents the null hypothesis and H1 represents the alternative hypothesis.

"The mean reading comprehension scores of students using the old method has a value of 46.3"

Above is the initial claim or assertion about the mean reading comprehensive scores of students.

This is the null hypothesis.

It can be written as

H' : u = 46.3

Where u = population mean.

The alternative hypothesis is a claim in opposition to the null hypothesis.

Hence the possible alternative hypothesis to the null will be

H1: u > 46.3 ( upper tailed)

H1: u < 46.3 ( lower tailed)

H1: u ≠ 46.3 (two tailed)

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6

answer: the answer is c.
