The Department of Education would like to test the hypothesis that the average debt load of graduating students with a bachelor's degree is equal to $17,600. A random sample of 28 students had an average debt load of $18,800. It is believed that the population standard deviation for student debt load is $4800. The a is set to 0.05. The confidence interval for this hypothesis test would be ($17,022.05, $20,577.95] ($14,352.73, $20,847.37] O $16,513.53, $18,686.47] [$15,072.93, $20,127.07] Question 20 1...

Consider the following competing hypotheses: He: =0,HA:#0. The value of the test statistic is za -1.46. If we choose a 1% significance level, you would reject the null hypothesis because there is not a difference in the two populations. True False

The Department of Education would like to test the hypothesis that the average debt load of graduating students with a bachelor's degree is equal to $17,000. A random sample of 34 students had an average debt load of $18,200. It is believed that the population standard deviation for student debt load is $4,200. The α is set to 0.05. The confidence interval for this hypothesis test would be ________.

Consider the following competing hypotheses: Use Table 2. H0: μD ≥ 0; HA: μD < 0 d-bar = −4.3, sD = 7.2, n = 15 The following results are obtained using matched samples from two normally distributed populations: a. At the 1% significance level, find the critical value(s). (Negative value should be indicated by a minus sign. Round intermediate calculations to 4 decimal places and final answer to 2 decimal places.) Critical value b. Calculate...
