A population of values has a normal distribution with \( \mu=111.2 \) and \( \sigma=39 \). You intend to draw a random sample of size \( n=231 \). Please show your answers as numbers accurate to 4 decimal places. Find the probability that a single randomly selected value is between 109.1 and 116.8 . \( P(109.1<X<116.8)=\square \)

At a festival, one game involves guessing the number of candies in a plastic jar. The following data represents the guesses that people made during one hour at the festival. Complete the frequency table for this data. \[ 1382,1211,1354,1171,1058,1472,1132,1090,1132,1443,1163,1274,1112,1266,1254,1174 \]

Determine the point estimate of the population mean and margin of error for the confidence interval. Lower bound is 21 , upper bound is 29 . The point estimate of the population mean is 1

A survey of 2283 adults in a certain large country aged 18 and older conducted by a reputable polling organization found that 406 have donated blood in the past two years. Complete parts (a) through (c) below. Click here to view the standard normal distribution table (page 1).

Derk Determine the point estimate of the population proportion, the margin of error for the following confidence interval, and the number of individuals in the sample with the specified characteristic, \( x \), for the sample size provided. Lower bound \( =0.529 \), upper bound \( =0.831, n=1500 \) The point estimate of the population proportion is 0.68 . (Round to the nearest thousandth as needed.) The margin of error is (Round to the nearest thousandth as needed.)

The grades on the second statistics test for Mrs. Sweeney's class are in the following list. Find the frequency distribution for the grades. \[ \text { D, F, B, D, A, F, F, B, F, F, B, C, C, C, B, F, C, A, B B, B F } \] Answer
