Ho: o = 0.2
H1: o > 0.2
What parameter is being tested - Answer: Population standard deviation
Because the symbol used in the hypotheses is sigma.
Recall that ir represents a population mean, sigma
Represents a population standard deviation, and p represents a population proportion
Ho: p = 0.2
H1: p < 0.2
What parameter is being tested - Answer: Population proportion
Because the symbol used in the hypotheses is p.
Recall that ir represents a population mean, sigma
Represents a population standard deviation, and p represents a population proportion.
Ho: ir = 4
H1: ir no = 4
What parameter is being tested - Answer: Population mean
Explain what a P-value is. What is the criterion for rejecting the null hypothesis using the
P-value approach? - Answer: A P-value is the probability of observing a sample statistic
as extreme or more extreme than the one observed under the assumption that the
statement in the null hypothesis is true.
Explain what "statistical significance" means. - Answer: When an observed result is
unlikely under the assumption that the null hypothesis is true, it is said the result is
"statistically significant" and the null hypothesis is rejected.
