Researchers investigated how the size of a bowl affects how much ice cream people tend to scoop when serving themselves. At an "ice cream social," people were randomly given either a 17-oz or a 34-oz bowl (both large enough that they would not be filled to capacity.) They were then invited to scoop as much ice cream as they liked. Did the bowl size change the selected portion size? The summaries are shown. Test an appropriate hypothesis and state your conclusions. For assumptions and conditions that you cannot test, you may assume that they are sufficiently satisfied to proceed. (Assume à significance level of 0.10.) Identify the null and alternative hypotheses. Choose the correct answer below. A. Ho: HL-Hs = 0 HA: HL-Hs #0 B. Ho: HL-Hs = 0 HA:HL-HS >0 O C.

Please help me in answering the following practice question:Given a random sample of the amount of protein (in gram) in one bag of snack food: 0.95, 0.85, 0.92, 0.95, 0.93, 0.86, 1, 0.92, 0.85, 0.81, 0.78, 0.93, 0.93, 1.05, 0.93, 1.06, 1.06, 0.96, 0.81, 0.96 Here, it is assumed that the amount of protein in the snack is normal. How would I calculate a 98% two-sided confidence interval for the average amount of protein in one bag?Thank you for your help in advance!
