According to a survey in a country 34% of adults do not own a credit card. suppose a simple random sample of 900 adults is obtained.
1) Determine the Mean of the sampling distribution P hat?
2) Determine the standard deviation of the sampling distribution p hat?
3) What is the probability that in a random sample of 900 adults more than 35% do not own a credit card?
The probability is: (Round four decimal places)
4) If 100 different random samples of 900 adults were obtained one would expect ____ to result in more than 35% not owning a credit card(round to nearest integer?
5) What is the probability that in a random sample of 900 adults between 30% and 35% do not own a credit card? The probability is______ (round four decimal places)
6) If 100 different random samples of 900 adults were obtained one would expect _____ to result in between 30% and 35% not owning a credit card (round to nearest integer)
