The kurtosis of a probability distribution is 2, per Microsoft
Excel. Which of the following characterizations is correct?
Group of answer choices
The tails of the distribution are lighter than the normal distribution
The tails of the distribution are similar to that of the normal distribution
The tails of the distribution are heavier than the normal distribution
The distribution is platykurtic
Given
The kurtosis of distribution is 2
Hence we say that
The tails of the distribution are heavier then normal distribution.
Becouse when kurtosis is greater than zero then distribution have heavier tails.

Which of the following is incorrect about the shape of distributions? a. Kurtosis is a measure of whether the data are heavy or light-tailed relative to a normal distribution. b. A distribution that is more peaked than normal is leptokurtic. c. Skewness is a measure of the lack of symmetry for a data set. d. All of the above are correct.
Binomial Distribution Use technology (calculator, Microsoft Excel, or Google Sheets) to find the following binomial probabilities. Round to the nearest thousandth. According to the Center for Disease Control, 15% of US adults are estimated to have chronic kidney disease. A random sample of 150 U.S adults are selected. What is the probability that: 1. Exactly 35 have chronic kidney disease? P(r = 35) = 0.002 2. No more than 15 have chronic kidney disease? P(r <$15) = 0.049 3. Thirty...
Microsoft Excel Question Which of the following 4 options is the correct answer for this question ? How does the SUM function handle cells that do not contain a number? Excel treats text cell values as 1. If there are no numbers in the SUM range, Excel displays an error message. Excel doesn't let you enter a SUM function if the range contains any nonnumerical values. Excel displays an error if any of the cells in the SUM range contain...
Which of the following is a correct description of the t-distribution? Select one: a. It is the best distribution to use with small sample sizes. b. There are fewer scores in the tails than in a normal distribution. c. It is equal to a normal distribution with infinite degrees of freedom. d. It is the best distribution to use when the population might be right or left skewed.
