Question

a A and store B. The stores ket their oniginal names and astmers can purchase products rom ater webale websites, tho distnibution of the amounts purchased will be bimodel Use this inormation to compiete parts (a) and (b) a random sample (a) As the sample size increases, what is the expected shape of the dstibution of amounts purchased in the sample? O A As the sample O B. As the sample size increases, the sample distribution OC. As the sampie size increases, the sample distrbution of amounts purchased will skew to the w O D. As the sample size increases, size increases, the sample distribution of amounts punchased will skew to the right of amounts purchased will look more and more lke the Normal distribution the sample distrbution of amounts purchased will look mone and more ike the population distribution, bimodal /b) As the sample size increases, what is the expected shape of the sampling modal for the mean amount parchased of the smple? O A As the sample size increases, the expected shape of the sampling model for the mean will be Nomal OB. As he sample size increases, to expected shape of to samping mak to mean wil-tot-ght O C. As the sample size increasos, the expected shape of the sampling model for the mean will skew to the le O D. As the sample size increases, the expected shape of the sampling model for the mean will aso be bid

Explanation / Answer

Solution:

(a) option (B) is correct.

As the samole size increase, the sapmle distribution of amounts purchased will look more and more like the normal distribution.

Reason:

When we increse the sample size sampling distribution will forllow normal distribution.

(b) option (A) is correct .

As the sample size increase, the expected shape of the sapming model for the mean will be normal.

Reason:

According to Central limit theorem, when we increase the sample size sampling distribution of sample mean will follow normal distribution.
