In the province of Jaén there are 50 thousand 523 homes, of which 24 thousand 882 are of the urban area. It is desired to know the status of the same, knowing that by studies previous p= 0.60 How many homes should be chosen in each area, using a level 95% confidence level, and a 6% error?

The average sales of a company are 15 thousand new soles and the variance of 4. What size should the sample be, with a confidence level of 95% and an error of 5%?

Suppose that variable X in a population has a distribution with mean 25 and standard deviation 4. If we choose a simple random sample of 50 people, what is the probability that the sample mean lies between 23 and 26? Show your approach.

Consider X, a variable whose distribution is normal with a mean of 5 and a variance of 2. We obtain the variable Z by standardizing X. If the value of z is -1 for an individual, what is the value of x for that same individual? Show your approach. (1 point).

Suppose we want to calculate a 94% confidence interval for a sample mean with a sample size n=54. We ignore the variance of the variable in the population. What is the numerical value corresponding to the order quantile used in calculating the confidence interval? Show your approach
