Which of the following are required to use the t test (remember there is both the variable you are testing and the grouping variable)?   a. An Interval variable   b. A Dichotomous variable   c. Neither a nor b   d. Both a and b

Let a, b > 0. Show that the geometric mean ,Jab is not larger than the arithmetic mean (a+ b)/2. Hint: Consider (a 1/2 - b 1/2)2.

Which statement is accurate about the relationship between Populations and Samples?     It is easier to test the entire population than to make inferences from a sample.     If a sample is selected randomly from a population then it will be exactly equal to the population.     Any difference between the population and the sample is known as sampling error     All 3 statements are true

Suppose there are 5 students in a room. The mean age is 19.8 years, and the median age is 19. If the youngest person leaves and is not replaced by another person, what happens to the mean and the median? O The mean and median increase. The mean increases, and the median either increases or stays the same. The mean increases, but it is impossible to determine whether the median increases, decreases, or stays the same. The mean increases, and the median stays the same. The median increases, and the mean either increases or stays the same.

A baseball team claims that the mean length of its games is more than 1.4 hours. State H0 and Ha in words and in symbols. Then determine whether the hypothesis test for this claim is​ left-tailed, right-tailed, or​ two-tailed. Explain your reasoning.       State the null hypothesis in words and in symbols. Choose the correct answer below.     A. The null hypothesis expressed in words​ is, "the mean length of a baseball​ team's games is not 1.4 ​hours." The null hypothesis is expressed symbolically​ as, ​"H0​: μ≠1.4​."   B. The null hypothesis expressed in words​ is, "the mean length of a baseball​ team's games is at least 1.4 ​hours." The null hypothesis is expressed symbolically​ as, ​"H0​: μ≥1.4​."   C. The null hypothesis expressed in words​ is, "the mean length of a baseball​ team's games is at most 1.4 ​hours." The null hypothesis is expressed symbolically​ as, ​"H0​: μ≤1.4​."   D. The null hypothesis expressed in words​ is, "the mean length of a…
