An ambulance service responds to emergency calls for two counties in virginia. one county is an urban county and the other is a rural county. a sample of 471 ambulance calls over the past two years showed the county and the day of the week for each emergency call. data are as follows. test for independence of the county and the day of the week. using a .05 level of significance, what is the p-value and what is your conclusion?

Iwill give ! if m∠a=59 and m∠3=81°, what is m∠b? m∠b= _[blank]_°

(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.)
