For a chi-square test involving a contingency table, suppose the null hypothesis is rejected. We conclude that the two variables are __________. a) related b) curvilinear c) linear d) not related 4. A sales manager for an advertising agency believes that there is a relationship between the number of contacts that a salesperson makes and the amount of sales dollars earned. What is the dependent variable?
1. A random sample of size 15 is selected from a normal population. The population standard deviation is unknown. Assume the null hypothesis indicates a two-tailed test and the researcher decided to use the 0.10 significance level. For what values of t will the null hypothesis not be rejected?
5. A test statistic is a value determined from sample information used to reject or not reject the null hypothesis. 6. The region or area of rejection defines the location of all those values that are so large or so small that the probability of their occurrence under a true null hypothesis is rather remote. 7.
Reject the null hypothesis if computed z is 1.96 or greater. B. Do not reject the null hypothesis if computed z is 1.65 or greater. C. Reject the null hypothesis if computed z is less than 1.96. D. Do not reject the null hypothesis if the z test statistics is 1.96 or greater.
Find and interpret βˆ1in the context of this problem. c. Find and interpret the coefficient of determination (r-squared). d. Find and interpret coefficient of correlation. e. Does the data provide significant evidence (= .05) that the number of calls can be used to predict the sales? Test the utility of this model using a two-tailed test.
So, 2000 = 30000/Square root of sample size. Solving for the Square root of sample size, we get Square root of sample size = 30000/2000 = 15. Taking its square, the sample size is found as 225. Chapter 9 Exercise 1 No it is not a good defense. If you choose 40 random employees from the corporation, the standard error would equal 6/Square root of 40 = .95 days.
a. equivocation b. illicit minor c. four-terms fallacy d. invalid conversion Question 2 A basic form of deductive argument is ________. a. inductive reasoning. b. the proposition. c. causation. d. the syllogism.
TOPIC 8 Chi-Square goodness-of-fit test Problem 12.1 Use a chi-square goodness-of-fit to determine whether the observed frequencies are distributed the same as the expected frequencies (α = .05) Category | fo | fe | 1 | 53 | 68 | 2 | 37 | 42 | 3 | 32 | 33 | 4 | 28 | 22 | 5 | 18 | 10 | 6 | 15 | 8 | Step 1 Ho: The observed frequencies are distributed the same as the expected frequencies Ha: The observed frequencies are not distributed the same as the expected frequencies Step 2 df = k – m – 1 Step 3 α = 0.05 x 2 0.05, 5df = 11.0705 Step 4 Reject Ho if x 2 > 11.0705 Category | fo | fe | | 1 | 53 | 68 | | 2 | 37 | 42 | | 3 | 32 | 33 | | 4 | 28 | 22 | | 5 | 18 | 10 | | 6 | 15 | 8

9). The rotation of perishable goods can be improved by conducting a survey and a questionnaire to the customer to indicate the needs of customer. Analyzing a turnover ratio per capital of each product will minimize the perishable rates. If a proper turnover ratio were set for the operation of buying and stocking of a product, KFF can easily expect what to expense and when to allocate the budget cutting the loss of excessive supply of the product. Specialty Shops Because KFF offers sophisticated professions such as butcher, baker, and wind steward, “payroll of these specialty positions is higher than that of the clerks and stock personnel” (KFF strategic plan, p. 9).
