There is u very popular lottery in which a ticket is called a scratcher. In this lottery, 43% of the scratchers are winning ones. Suppose that we will take a random sample of 10 scratchers. Let p represent the proportion of winning scratchers from the sample. Consider the sampling distribution of the sample proportion p. Complete the following. Carry your intermediate computations to four or more decimal places. Write pur answers with two decimal places, rounding if needed (a) Find LA (the mean of the sampling distribution of the sample proportion). HA =| (b) Find on (the standard deviation of the sampling distribution of the sample proportion).

### Sampling Distributions of a Sample Proportion

There is a very popular lottery in which a ticket is called a scratcher. In this lottery, 43% of the scratchers are winning ones. Suppose that we will take a random sample of 10 scratchers. Let \( \hat{p} \) represent the proportion of winning scratchers from the sample. Consider the sampling distribution of the sample proportion \( \hat{p} \).

Complete the following steps. Carry your intermediate computations to four or more decimal places. Write your answers with two decimal places, rounding if needed.

#### (a) Find \( \mu_{\hat{p}} \) (the mean of the sampling distribution of the sample proportion).

\[ \mu_{\hat{p}} = \boxed{} \]

#### (b) Find \( \sigma_{\hat{p}} \) (the standard deviation of the sampling distribution of the sample proportion).

\[ \sigma_{\hat{p}} = \boxed{} \]
