Answer:
A sample of 752 should be taken.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the z-score that has a p-value of .
The margin of error is of:
90% confidence level
So , z is the value of Z that has a p-value of , so .
No preliminary sample is taken
This means that
How large should the sample be to be 90% sure that the estimate is within .03 of the population proportion?
This is n for which M = 0.03. So
Rounding up:
A sample of 752 should be taken.

Answer:
As the probability of X less than or equal to 23.6474819 and the probability of X is less than or equal to -0.1909414, as the points are less than the condition, then there are unusual and equal to an unusual situation.
Step-by-step explanation:
A z score measures the standard deviation below and above the mean of data. A formula for calculating z-score is
Essential facts about z-scores:
If data is above average, then the z-score is positive.
If data is below average, then the z-score is negative.
if the point is close to average, then z-score is close to 0
if the point is above 333 or blows 3 then z score is unusual.
As the probability of X less than or equal to 23.6474819 and the probability of X is less than or equal to -0.1909414, as the points are less than the condition, then there are unusual and equal to the unusual situation.
