Question

Here is my question, please tell me exactly what to put in every space needed/if wat I already have is wrong. Thanks very much! :)

An industrial psychologist is investigating the effects of industrial lighting on workforce production. Eight workers are subject to lighting A, and six others are exposed to lighting B. The number of widgets they are able to assemble per hour is the measure of production. The number of widgets assembled are as follows: Lighting A: 8, 11, 6, 10, 8, 12, 7, 10 Lighting B: 14, 15, 9, 16, 11, 13 Does industrial lighting type influence workforce production? Solve this problem explicitly using the appropriate null hypothesis testing procedure, and set the alpha at 5%. Formulate the null and research hypothesis Research: Null: 1= 2 What are the characteristics of the comparison distribution? Mean: Standard deviation:

Explanation / Answer

Below are the null and alternate hypo
H0: mu1 = mu2
H1: mu1 not equals mu2 (research hypo)

mean = 0 (comparison difference)

std. dev. = 1.2919

As this is two tailed, the rejection region would be on the both sides.
+/- 2.2622

The test statistic is extreme enough we therefore reject the null hypothesis.

Given Data Sample 1 Sample 2 Name mean 9 13 Sample size 8 6 Std. dev. 2.07 2.61
