After reading the following Chapters Hypothesis Testing, Measures of Association and Multivariable analysis, answer the questions below.
1. A researcher hypothesizes that children who learn
to read using phonics will read better than those not taught in
this manner. Identify H0 and Ha. Is this a
one- or two-tailed test?
2. If a researcher decides to use the .01 level of
significance rather than using the more conventional .05 level of
significance, what type of error is more likely to be made?
Why?
3. Do the attached exercise. Enter the data shown in the exercise in the excel sheet to find the responses to the questions.
4. What multivariate technique would you use to analyze each of the following problems? Explain your choice.
a. Employee job satisfaction (high, normal, low) and employee success (0-2 promotions, 3-5 promotions, 5+ promotions) are to be studied in three different departments of a company.
Answer 1=
Ho: No help in reading better
Ha: They can read better by using phonic
This is a one-tailed test
Answer 2= here will be a Type II mistake
If the risk of having a false alarm is controlled, then there
are greater chances of missing the difference which could exist in
actual

Hypothesis Testing Method A = ADKAR Framework (column A) Method B = Prosci Change Management Methodology (column B) Null hypothesis is H0: Method A = Method B Research (Alternative) hypothesis is H1:Method A < Method B Sample size: 30 One-tailed test: Direction stated in the hypothesis is determine more effective (greater or less than). Level of Significance (a): .05 t-test is used because standard deviation of population is unknown, sample size is less than 30 Cutoff Sample Score (critical value)...
1. We reject the null hypothesis only when: a. our sample mean is larger than the population mean. b. the p value associated with our test statistic is greater than the significance level of the test we have chosen. c. our sample mean is smaller than the population mean. d. the p value associated with our test statistic is smaller than the significance level of the test we have chosen. 2. In a study of simulated juror decision making, researchers...
