Please answer A, B, C Thanks! only used for Class Discussion Exercise Kayla Reed is using mean-per-unit estimation in the audit of Hamilton's inventory balances. Hamilton's inventory is recorded at $240,000 and comprises 1.200 different items. Reed determined a sample size of 120 items and performed the appropriate substantive procedures and based on this sample, determined the following: Average audited value (per item) Standard deviation of audited values $ 204 $ 22 A summary of some additional parameters estimated by...

Which of the following is NOT an assumption about nonparametric tests? a.They do not involve the estimation of population parameters. b.The expected frequencies are based on the row and column frequencies for a sample rather than on assumptions regarding how frequencies for the two variables are distributed in the population c. Data from a sample is being used to estimate the population parameter. d.They do not require variables to be normally distributed.
_________ refers to the use of sample data to calculate a range of values that is believed to include the value of the population parameter. a. Statistical inference b. Hypothesis testing c. Interval estimation d. Point estimation
A list contains three distinct values, a < b < c. Depending on the relative frequencies of the values in the list, the list could be nearly normally distributed. Answer: False. Can some please explain why this is false?
A frequency table of grades has five classes (A, B, C, D, F) with frequencies of 4, 10, 13, 5, and 3 respectively. Using percentages, what are the relative frequencies of the five classes? Complete the table. This is for my Statistics class
