A population has parameters = 178.3 and & = 25.5. You intend to draw a random sample of size n = 202, What is the mean of the distribution of sample means? bz = What is the standard deviation of the distribution of sample means? (Report answer accurate to 2 decimal places.) TF Question Help: []Video A particular fruit's weights are normally distributed, with a mean of 579 grams and a standard deviation of 9 grams.

Question Help: [] Video A population of values has a normal distribution with = 165.3 and o0 = 78.4. You intend to draw a random sample of size n = 23. Find the probability that a single randomly selected value is greater than 175.1. P(X=175.1) = Find the probability that a sample of size n = 23 is randomly selected with a mean greater than 175.1. P(M > 175.1) = Enter your answers as numbers accurate to 4 decimal places. Answers obtained using exact z-scores or z- scores rounded to 3 decimal places are accepted.
