Suppose a random sample of n = 16 observations is selected from a population that is normally distributed with mean equal to 101
stepan [7]

Answer:

101, 3, 0.025, 0.7416

Step-by-step explanation:

Given that  a random sample of n = 16 observations is selected from a population that is normally distributed with mean equal to 101 and standard deviation equal to 12.

As per central limit theorem we have

a) Mean of sample mean = E(\bar x) =\\ \mu =101

Std deviation of sample mean = \frac{\sigma}{\sqrt{n} } =3

Mean = 101

Std dev =3.00

b) P(\bar x >107) = P(Z>\frac{107-101}{3} )\\= P(Z>2) = 0.025

c) the probability that the sample mean deviates from the population mean μ = 101 by no more than 4.

=P(|\bar x-101|) \leq 4\\= P(|z|\leq 1.13)\\= 2(0.3708)\\=0.7416

X : 1

39/4 ÷ 9/2 = X/1

39/4 × 2/9 = X

13/6 = X

X = 2⅙
