Crossing Ontario Between 1954 and 2003, swimmershave crossed Lake Ontario 43 times. Both women andmen have made the crossing. Here are some plots (we’veomitted a crossing by Vikki Keith, who swam a roundtrip—North to South to North—in 3390 minutes): How much difference is there between the mean amount of time (in minutes) it would take female and male swim-mers to swim the lake? a) Construct and interpret a 95% confidence interval forthe difference between female and male times.b) Comment on the assumptions and conditions.

According to a polling organization, 22% of adults in a large region consider themselves to be liberal. A survey asked 200 respondents to disclose their political philosophy: Conservative, Liberal, Moderate. Treat the results of the survey as a random sample of adults in this region. Do the survey results suggest the proportion is higher than that reported by the polling organization? Use an a = 0.01 level of significance. E Click the icon to view the survey results. Because npo (1- Po) =| > 10; the sample size is less than 5% of the population size, and the sample is given to be random, the requirements for testing the hypothesis satisfied. are (Round to one decimal place as needed.)
