According to the CLT, the standard error A. decreases, gets smaller as the sample size n B. decreases, gets larger C. stays the same, gets larger D. increases, gets larger

Sadie deals 5 cards from a standard deck of 52 cards. She would like to deal as many spades as possible. Is it reasonable to approximate this distribution with a normal distribution? Give a reason.

The football coach randomly selected fifteen players and timed how long each player took to perform a certain drill. The times (in minutes) were: 3.5, 3.3, 3.2, 4.7, 4.4, 3.5, 3.9, 4.5, 4.8, 5.2, 5.4, 4.0, 4.3, 4.1, 5.1 (a) Show that this data approximates a normal distribution.   (b) Determine a 90% confidence interval for the mean time for all players.

The mean of a sampling distribution is smaller than the mean of the underlying population. True or false

As the sample size​ increases, the mean of the sampling distribution ▼   stays the same. gets larger. gets smaller.

Suppose the percentage of married couples who own a home is 33% for a given population. What is the standard error of the sampling distribution of proportions for the sample sizes n = 200, n = 300, and n = 400?
