Marina volunteers at the Salvation Army. She has been tasked with buying nonperishable items for families that were displaced by a recent flood. She finds a company willing to sell her cans of food at a discounted price of $2.25 for a small can and $4.75 for a large can. She spent a total of $714.75 and bought 181 cans. Let x represent the number of small cans she purchased and y represent the number of large cans she purchased.

(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.)
