A hypothesis test for a population proportion p is given below: H0: p = 0.10. Ha: p 010. For each sample size n and sample proportion compute the value of the z-statistic: Sample size n = 100 and sample proportion = 0.10. z-statistic = ? –1.00. 0.00 0.10 1.00 Sample size n = 100 and sample proportion = 0.15. z-statistic = ? –1.12
