An economist wants to estimate the mean per capita income (in thousands of dollars) for a major city in Texas. Suppose that the mean income is found to be $23.4$ 23.4 for a random sample of 976976 people. Assume the population standard deviation is known to be $10$ 10. Construct the 95%95% confidence interval for the mean per capita income in thousands of dollars. Round your answers to one decimal place.

The 95% confidence interval for the mean per capita income in thousands of dollars is between $22.8 and $24.

Step-by-step explanation:

We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of .

So it is z with a pvalue of , so

Now, find the margin of error M as such

In which is the standard deviation of the population and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 23.4 - 0.6 = $22.8.

The upper end of the interval is the sample mean added to M. So it is 23.4 + 0.6 = $24.

The 95% confidence interval for the mean per capita income in thousands of dollars is between $22.8 and $24.

you forgot the options, but i found them anyways, the correct answer is "john wilson believes that words and actions based on the intellect are superior to those based on emotions".

john wilson is depicted as an extremely intelligent man. the point of the excerpt is to make a sort of distinction between emotional and rational intelligence. he happens to have both attributes, but he clearly favors his intellectual gifts. at the same time, because of his religious background, he's a little bit conflicted with this and it makes him ashamed.

hope this !
