Draw a normal curve with  b= 20 and a = 3.(b) Shade the region that represents p(22 ≤ x ≤ 27) and find the probability. Note that x represents a normalrandom variable with distribution described in part (a) and that p represents the probability for x to take arange of values.

Previous studies have suggested that human body temperature is normally distributed with a mean of 98.6∘ F and a standard deviation of 0.7∘ F. You sample 35 random humans and find ¯x=99∘ F. To estimate the typical human's body temperature,we should use: TInterval 2-PropZInt 2-SampTInt 2-SampZInt ZInterval 1-PropZInt

Use the central limit theorem to find the mean and standard error of the mean of the indicated sampling distribution. Then sketch a graph of the sampling distribution. The per capita consumption of red meat by people in a country in a recent year was normally distributed, with a mean of 117 pounds and a standard deviation of 39.8 pounds. Random samples of size 20 are drawn from this population and the mean of each sample is determined. = μx ox (Round to three decimal places as needed.) = Sketch a graph of the sampling distribution.
