The process that produces sonora bars (a type of candy) is intended to produce bars with a mean weight of 56 gm. the process standard deviation is known to be 0.77 gm. a random sample of 49 candy bars yields a mean weight of 55.82 gm. which are the hypotheses to test whether the mean is different than it is supposed to be? assume that candy bar weights are normally distributed.
select one:
a. h0: μ ≤ 56, ha: μ > 56
b. h0: μ ≥ 56, ha: μ < 56
c. h0: μ = 56, ha: μ ≠ 56
d. h0: μ < 56, ha: μ ≥ 56

Colby and jaquan are growing bacteria in an experiment in a laboratory. colby starts with 50 bacteria in his culture and the number of bacteria doubles every 2 hours. jaquan starts with 80 of a different type of bacteria that doubles every 3 hours. let x equal number of days. colbys experiment follows the model: a.) y=50*2^x b.) y=50*2^8x c.) y=50*2^12x jaquans experiment follows the model: a.)80*2^x b.)80*2^8x c.)80*2^12x
