Bill bought a new cellular phone. his monthly bill will be $32.99 each month which includes 100 minutes of use. additional minutes will cost $0.19 per minute. write a linear model that represents the amount of the bill, c, based on the total number of minutes, m, the phone is used in a month. assume m > 100 minutes.
a. c= 0.19m+32.99
b. c= 32.99(m-100)+0.19
c. c= 0.19m
d. 0.19(m-100)+32.99

An automobile assembly line operation has a scheduled mean completion time, μ, of 12 minutes. the standard deviation of completion times is 1.6 minutes. it is claimed that, under new management, the mean completion time has decreased. to test this claim, a random sample of 33 completion times under new management was taken. the sample had a mean of 11.2 minutes. assume that the population is normally distributed. can we support, at the 0.05 level of significance, the claim that the mean completion time has decreased under new management? assume that the standard deviation of completion times has not changed.
