Question

A sample of five measurements, randomly selected from a normally distributed population, resulted in the following summary statistics: x = 4.8,s = 1.3 Test the null hypothesis that the mean of the population is 6 against the alternative hypothesis, mu < 6. use alpha =.05. Test the null hypothesis that the mean of the population is 6 against the alternative hypothesis, mu 6. Use alpha =.05 Find the observed significance level for each test.

Answer 1

Answer:

a. null hypothesis is rejected.

b. null hypothesis is rejected.

c.

For (a); 0.05 < P < 0.100

For (b) 0.100 < P < 0.200

Step-by-step explanation:

Given

Number of samples, n = 5

Mean, x = 4.8

Standard Deviation, s = 1.3
