Answer:

2.810  log3(21.903)

Step-by-step explanation:

log5(92) = 2.810

To change bases

logb(a) = logc(a) / logc(b)

 where c is the new base and b is the old base

log5 (92) = log 3(92)/log3(5)

The proportion of left handed people in the population is about 0.10. Suppose a random sample of 300 people is observed. (a) Wha
pantera1 [17]

Answer: (\hat{p})\sim N(0.10,\ 0.017)

Step-by-step explanation:

Sampling distribution of the sample proportion (\hat{p}) :

(\hat{p})\sim N(p,\ \sqrt{\dfrac{p(1-p)}{n}})

The sampling distribution of the sample proportion (\hat{p}) has mean = \mu_{\hat{p}}=p and standard deviation = \sigma_{\hat{p}}=\sqrt{\dfrac{p(1-p)}{n}}.

Given : The proportion of left handed people in the population is about 0.10.

i.e. p=0.10

sample size : n= 300

Then , the sampling distribution of the sample proportion(\hat{p}) will be :-

(\hat{p})\sim N(0.10,\ \sqrt{\dfrac{0.10(1-0.10)}{300}})

(\hat{p})\sim N(0.10,\ \sqrt{0.0003})

(\hat{p})\sim N(0.10,\ 0.017)  (approx)

Hence, the sampling distribution of the sample proportion(\hat{p}) is (\hat{p})\sim N(0.10,\ 0.017)
