I need help with D and E

that there is a difference between the proportion p₁ of all items to North America that are overweight and the proportion p₂ of all items on English Air flights within Europe that are overweight? Perform a two-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the parts below. (If necessary formulas.) (a) State the null hypothesis Ho and the alternative hypothesis H₁. Ho :P₁ = P₂ H₁ P₁ P₂ (b) Determine the type of test statistic to use.

English Air continually monitors the proportion of overweight items checked by passengers on its flights in order to evaluate the appropriateness of their overweight fees. Recently, a random sample of 289 items checked on English Air flights to North America contained 54 overweight items, and an independent, random sample of 297 items checked on English Air flights within Europe contained 32 overweight items. Based on these samples, can we conclude, at the 0.01 level of significance, that there is a difference between the proportion p₁ of all items on English Air flights to North America that are overweight and the proportion p, of all items on English Air flights within Europe that are overweight? Perform a two-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the parts below.
