Discussion Topic Many types of bias exist when it comes to surveys, including nonresponse bias,
undercoverage, and poorly worded survey questions. Think about a survey you've been
asked to participate in. Maybe it was printed on a fast-food receipt or a store directed
you to an online survey after you made a purchase. What influenced you to participate
in the survey or to opt out of participating?

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
