Please assist to detail the find by step for the following:

The average height of a female adult in Australia is 175.6cm, with variance 25cm,  find the probability that a randomly selected man measures between 178 and 184 centimetres.  

Assuming a normal distribution

Solutions

Expert Solution

given data .

here we have to faindout Z values for 178 cm & 184cm

= 0.48

= 1.68

Form normal distribution table

P(Z) we will findout.

P(0.48) =0.6844

P(1.68) =0.9535

probability for getting man between 178 & 184 is

P(178 < Xi < 184) = P(Z(184)) -P(z(178))

= P(1.68) -P(0.48)

= 0.9535 -0.6844

= 0.2691

Probability for getting man between 178 & 184 is 0.2691 ie,. 26.91%

step by step please. It is reported that a 95% confidence interval for the population average of a variable X normally distributed is [37.1;46.9]. Consider that the population standard deviation is 12.5 and that the interval was obtained considering a population of infinite size. If P (Z> 1.96) = 0.025, what is the sample size used in this study?
