Been practicing and trying to make sure i got the answers right so need some help please.

A...At a large university, 38% of the students are in favor on a $20 fee increase to pay for additional health services. If a random sample of 110 students is chosen, andp^= proportion of students who are in favor of the fee increase,what are the mean and standard error for the sampling distribution ofp^?

p^= ?

p^= ? (Round to 3 decimal places)

B...In a large metropolitan city, 63% of the population take public transportation to work. If a random sample of 250 people are chosen, andp^=proportion of people who take public transportation, thenapproximately 95% of the possible sample proportions (p^)will be between and (Round your answers to 3 decimals).

C...In a town, 32% of the people own a dog. If a random sample of 300 are chosen, what is the probability that more than 108 own a dog?

To answer this question you will need the following:

A) What is the mean ofp^? p^=

B) What is the standard error ofp^? p^ = (round to 3 decimal places)

C) What is the sample proportion? p^= ?

D) Find the probability that more than 108 people in the sample own a dog. (give your answer as 4 decimal places)

D...According to the National Center for Health Statistics, 13% of all Americans are hearing impaired.

In a random sample of 175 Americans, what is the probability that less than 10% have hearing problems? (Round your answer to 3 decimal places)

E....According to a study conducted by a research firm, 87% of Canadians are satisfied with the way things are going in their lives.

A) If a random sample of 170 Canadians is chosen, what is the probability the proportion of people who are satisfied with the way things are going exceeds 0.9?

B) Would it be unusual if, in a random sample of 170 Canadians, less than 0.79 are satisfied with their lives?

C) The probability the sample proportion is less than 0.79 P(p^< 0.79) =

F.....According to a marketing research firm, 29% of people do not own a credit card. If a random sample of 205 people are chosen, what is the probability that between 26% and 32% do not own a credit card? (Give your answer with 4 decimals).

G....In a recent election 54% of people supported reelecting the incumbent. Suppose a poll is done of 1250 people.

If we used the normal as an approximation to the binomial, what would the mean and standard deviation be?

Mean= Standard deviation=
