Which of the following is true with regards to the Earnings Per share (EPS)? Firms are required to report the EPS in the SEC filings All else equal, EPS can be lowered significantly if the firm issues new shares EPS is commonly discussed as a measure of short term earnings performance EPS is generally not the best way to compare performance of two dis-similar firms All of the Above
8. Assume the GPA of Stats II students is distributed normally with a population standard deviation of .10. To test whether the average GPA of Stats II students is GREATER THAN 3.12, a sample of size 49 was drawn and a sample mean of 3.16 was calculated. What is the test statistic? Select one: a. z = 2.10 b. z = 2.80 c. t = 2.10 d. z= 2.57
1. The distribution of heights of adult females: We assume that height is normally distributed with a population mean of 65 inches and a population standard deviation of 4 inches. 2. The distribution of heights of adult males: We assume that height is normally distributed with a population mean of 70 inches and a population standard deviation of 5 inches. a. Above what Z-score value does 2.5% of the normal distribution fall? Using the formula for Z-scores and the Z-score...
Assume the annual day care cost per child is normally distributed with a mean of $8000 and a standard deviation of $1500. In a random sample of 120 families that use day care, how many pay between $6500 and $8750 annually for day care per child? Round to the nearest whole number.
College students annual earnings are normally distributed with standard deviation σ-$800. If the mean earning for gro construct a 95% confidence interval estimate of the mean annual earnings for all college students. 10. up of 64 students is $4000,
1) What is the probability of a randomly selected value from a normally distributed population falling within 1.5 standard deviations of the mean? 8) What is the probability of a randomly selected value from a normally distributed population NOT being between 0.68 standard deviations below the mean and 1.5 standard deviations above the mean? ***For the following questions, assume a business has an average daily revenue of $1200 and revenue levels are found to be normally distributed with a standard...
The annual report of Dennis Industries cited these primary earnings per common share for the past 5 years: $2.42, $1.03, $2.08, $4.19, and $6.84. If we assume these are population values. What is the arithmetic mean primary earnings per share of common stock? (Round your answer to 2 decimal places.) Arithmetic mean B. What is the variance? (Do not round intermediate calculations. Round your answer to 2 decimal places.) Variance
For a normally distributed population with a mean of 35 and a standard deviation of 7.5, if a sample of 50 is taken from the population, what is the probability that the sample mean will be greater than 36.5?
For a normally distributed population with a mean of 35 and a standard deviation of 7.5, if a sample of 50 is taken from the population, what is the probability that the sample mean will be between 35 and 37.5?
Assume that a population is normally distributed with a mean of 100 and a standard deviation of 15. Would it be unusual for the mean of a sample of 3 to be 115 or more? Why or why not? Provide an example. There are many examples currently on the Chegg database, PLEASE use a DIFFERENT example. Thank you!
