1.Suppose that as a specialist in the field of signal detection you know that the population of air traffic control operators has a mean identification rate of 82 out of 100.You have just developed a new training system that will increase the number of targets correctly identified.Using the data from 15 trainees listed below, conduct a single sample t-test to determine whether they perform significantly different from the population of air traffic control operators trained using the traditional method.

a.State the null and alternative hypotheses

b.Set the criteria for a decision (it is done for you; SPSS uses the default of a two-tailed test witha= .05)

c.Compute the test statistic using SPSS

d. What is the effect size (you will need to compute Cohen'sdfrom data given in the SPSS output table)

e. Write the Results section for your findings.Include the descriptive statistics, type of statistical test and results of the test, effect size, Cohen'sdand the confidence interval.Use the example I've given you.

88 86 91

79 91 85

92 80 82

87 77 89

82 83 94

I also need to see at least some of the work to get these answers please, thank you!!!
