(14)Based on the Minitab output, what is the 95% CI for the population proportion p?

(round to the two placed in decimal)

(15)Write the confidence interval from (13) in the form: Point estimate Margin of Error

(16)Calculate the 95% CI from the information in (13) if the sample size is 15. (remember to check for the success-failure condition)

Hypothesis Testing for proportion

(17)When using normal approximation for distribution of for hypothesis testing,

one should always verify that is nearly normal under H₀ (meaning under the assumption that the null hypothesis (H₀) is true), this can be done by checking for the ________________and the ________________________________________

(18)If p_o represents the hypothesized population proportion, and if n is the number of trials, in order to use the normal approximation to the Binomial Distribution, both n*p_o and n*(1- p_o) are both ____________
