Answer:
c. binds to allolactose and becomes inactive, allowing lac gene expression to occur.
Explanation:
Interaction between allolactose and repressor leads to allosteric repulsion which makes repressor inactive leading to the lac gene expression. This is the reason why allolactose is known as the inducer of lac operon becasue it causes gene expression in lac operon.
In the absence of allolactose, the repressor binds the operator and does not allow RNA polymerase to do transcription.

Answer:
(a) H0: mu = 17 vs. Ha: mu < 17
(b) Sample statistic is 1.6
Explanation:
(a) A null hypothesis is a statement from a population parameter which is either rejected or accepted (fail to reject) the upon testing. It is expressed using the equality sign.
An alternate hypothesis is also a statement from a population parameter which negates the null hypothesis and is accepted if the null hypothesis is rejected. It is expressed using any of the inequality signs.
(b) Sample statistic = sample mean ÷ sample size = 16 ÷ 10 = 1.6
