Question

Select one answer for 1-20 1. For the t score distribution curve, identify its incorrect attribute All of its t scores are equally likely is Symmetric t 0 corresponds to the center of the distribution It changes shape with different values of the degrees of freedom 2. The test statistic is what we observed probability curve the likely and unlikely scores likely and unlikely 3. The p value is what we observed probability curve the likely and unlikely scores likely and unlikely 4. The critical values are what we observed probability curve the likely and unlikely scores likely and unlikely 5. Find Z o3 The probability of obtaining results as extreme as The computed score representing our data on a The values on a probability curve which separate The threshold probability for what is considered The probability of obtaining results as extreme as The computed score representing our data on a The values on a probability curve which separate The threshold probability for what is considered The probability of obtaining results as extreme as The computed score representing our data on a The values on a probability curve which separate The threshold probability for what is considered 1.88 1.88 .52 6. Identify the t-score, tnecessary for a two tailed hypothesis test for a population mean with a significance level of .05. Assume n 20 1.96 2.093 2.086

Explanation / Answer

1) First option is correct

All t scores are equally likely incorrect and rest are properties of T distribution

2)

Second option is correct

computed score representing data on a probability curve

3) first option is correct

4) 3rd option is correct

the values of a probability curve seperate likely or unlikely scores

5) Z alpha = -1.88

6) t critical = 2.093

7) H0

8) t

9) Z

10) 4th option is correct

(as per chegg guidelines, I have to do only 4 but I gave 10, because of simple questions)
