A population of values has a normal distribution with μ = 116.3 μ = 116.3 and σ = 60.6 σ = 60.6 . You intend to draw a random sample of size n = 22 n = 22 . Find the probability that a single randomly selected value is greater than 99.5. P(X > 99.5) = Find the probability that a sample of size n = 22 n = 22 is randomly selected with a mean greater than 99.5. P(M > 99.5) = 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.

Step 1
5 Given: μ = 116.3, σ = 60.6, x = 99.5 Calculate z-score: z = (99.5 - 116.3) / 60.6 = -0.277 Show more…

The expected mean of a continuous population is $100,$ and its standard deviation is $12 .$ A sample of 50 measurements gives a sample mean of 96. Using a 0.01 level of significance, a test is to be made to decide between "the population mean is 100 " and "the population mean is different from $100 . "$ State or find each of the following: a. $H_{o}$ b. $H_{a}$ c. $\alpha$ d. $\mu\left(\text { based on } H_{o}\right)$ e. $\bar{x}$ f . $\boldsymbol{\sigma}$ g. $\sigma_{x}$ h. $z *, z$ -score for $\bar{x}$ i. $p$ -value j. Decision k. Sketch the standard normal curve and locate $z \star$ and $p$ -value.
