Question

Hypothesis Test. Researchers suggest that, nationwide, college student populations have about 10% Type A personalities. Does North Georgia have a higher percentage? A recent survey showed a sample of 155 North Georgia students contained 22 students with Type A personalities.

Question: If the level of significance is 0.05, the correct statistical conclusion would be.

Question 7 options:

	Reject the alternative
	Accept the alternative
	Reject the null
	Accept the null
	None of these

Answer 1

Here the test statistic is,

Z Test of Hypothesis for the Proportion
Null Hypothesis            p =	0.1
Level of Significance	0.05
Number of Items of Interest	22
Sample Size	155
Intermediate Calculations
Sample Proportion = 22/155	0.141935484
Standard Error	0.0241
Z Test Statistic	1.7403
Two-Tail Test
Lower Critical Value	-1.9600
Upper Critical Value	1.9600
Do not reject the null hypothesis

Hence we accept the null Hypthesis.
