n a study of exhaust emissions from school buses, the pollution intake by passengers was determined for a sample of nine school buses used in the a school district. The pollution intake is the amount of exhaust emissions, in grams per person, that would be breathed in while travelling on the bus during its usual 10-mile trip on congested highways. Here are the amounts for the nine buses when driven with the windows open: 1.15 0.33 0.40 0.33 1.35 0.38 0.25 0.40 0.35 The data can be accessed HERE.Find a 90% confidence interval to estimate the population mean pollution intake μμ by completing the following.

State H0 and what is H1 for all of them a, b and c a) The marketing researcher would like to find out whether consumers from different regions evaluate brand A differently when they see the brand name b) The marketing researcher would like to find out whether consumers from the south region and the north region evaluate brand B differently when they see the brand name c. The data file contains four taste evaluations. The taste evaluations were measured on a scale from 1 to 10 (with 10 the highest evaluation). Brand equity of one brand for one respondent is the difference of branded score and unbranded score of that brand evaluated by the respondent.
