You are performing a study about weekly per capita milk consumption. A previous study found weekly per capita milk consumption to be normally distributed, with a mean of 42.5 fluid ounces and a standard deviation of 7.8 fluid ounces. You randomly sample 30 people and record the weekly milk consumptions shown below. 35 47 33 35 41 44 31 54 38 44 O 41 28 37 47 40 40 41 45 45 43 36 31 27 39 52 39 44 40 49 38 B. Yes, because the histogram is symmetric and bell-shaped. OC. Yes, because the histogram is neither symmetric nor bell-shaped. O D. No, because the histogram is symmetric and bell-shaped. (b) Find the mean of your sample. The mean is 40.1. (Round to one decimal place as needed.) Find the standard deviation of your sample. The standard deviation is (Round to one decimal place as needed.)
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
Could you please solve for the standard deviation with the given formula, I can't figure it out.
Thank you
