looking for help since checking my answers twice, I've ended up with multiple solutions and want to check if I correctly did my intervals right

2. A company with 2 delivery truck drivers is trying to figure out if one of the drivers is better than the other. They want to run a hypothesis test that the percent of times a driver made their delivery late is the same across the 2 drivers. They have collected the following data. Refer to Driver #1 as Population 1 and Driver #2 as Population 2, and answer the following questions leading up to the hypothesis test. Driver #1 (population 1) Driver #2 (population 2) Number of deliveries last month = 100 Number of deliveries last month = 140 Number of deliveries late last month = 28 Number of deliveries late last month = 28 Ho : P1 - P2 = 0 Ha : P1 - 2 # 0 (a) What is the estimate of the proportion in population 1? (b) What is the estimate of the proportion in population 2? (c) What is the estimate of the difference between the two population proportions? (d) What is the standard error of the difference between the two population proportions? Round to 4 decimal places. (e) Develop a 90% confidence interval for the difference between the two population proportions. Report as a number + another number. (f) Develop a 95% confidence interval for the difference between the two population proportions. Report as a number + another number. (g) Develop a 99% confidence interval for the difference between the two population proportions. Report as a number + another number. (h) What is the pooled estimate of p? (i) What is the test statistic (s-value)? Round to 2 decimal places. (j) What is the p-value? Round to 4 decimal places. (k) With a 90% confidence level (or = 0.10), what is your conclusion? (1) With a 95% confidence level (or = 0.05), what is your conclusion? (m) With a 99% confidence level (a = 0.01), what is your conclusion
