Assume that a simple random sample has been selected from a normally distributed population and test the given claim.

Use the P-Vakue method.

Below, dentify:

a) The null hypothesis

b) The alternative hypothesis

c) The test statistic

d) The P-value

e) The critical value(s)

f) The conclusion about the null hypothesis

g) The final conclusion that addresses the original claim.

A researcher wants to test the claim that convicted burglars spend an average of 18.7 months in jail. She takes a

random sample of 11 such cases from court files and finds that x = 20.6 months and s = 7.8 months. Test the

claim that µ = 18.7 months at the 0.05 significance level. Use the traditional method of testing hypotheses.

Below, identify:

a) The null hypothesis

b) The alternative hypothesis

c) The test statistic

d) The P-value

e) The conclusion about the null hypothesis

f) The final conclusion that addresses the original claim.

In a clinical study of an allergy drug, 108 of the 202 subjects reported experiencing significant relief from their

symptoms. At the 0.01 significance level, test the claim that more than half of all those using the drug experience

relief.

how would I solve this?
