Vedmedyk [2.9K]

Answer:

By the Central Limit theorem, the mean of the distribution of sample means is 643.6 minutes.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this problem

The mean of the population is 643.6 minutes.

By the Central Limit theorem, the mean of the distribution of sample means is 643.6 minutes.

HACTEHA [7]

Answer:

1×(4-3x)/5=1×(3x×4)/7

(4-3x)/5=(3x-4)/7

7(4-3x)=5(3x-4)

28-21x=15x+21x

28+20=15x+21x

48=36x

48/36=x

x=4/3
