# The average final exam score f

The average final exam score for the statistics course is 75%. A professor wants to see if the average final exam score for students who are given colored pens on the first day of class is lower. The final exam scores for the 14 randomly selected students who were given the colored pens are shown below. Assume that the distribution of the population is normal.

74, 71, 74, 59, 77, 50, 50, 65, 61, 68, 73, 71, 63, 76

What can be concluded at the the αα = 0.10 level of significance level of significance?

1. For this study, we should use Select an answer z-test for a population proportion t-test for a population mean Correct
2. The null and alternative hypotheses would be:

H0:H0:  ? μ p Correct Select an answer ≠ > = < Incorrect Incorrect

H1:H1:  ? μ p  Select an answer ≠ < = > Incorrect Incorrect

1. The test statistic ? t z Correct = Incorrect (please show your answer to 3 decimal places.)
3. The p-value is ? ≤ >  αα
4. Based on this, we should Select an answer accept reject fail to reject Correct the null hypothesis.
5. Thus, the final conclusion is that …
• The data suggest the population mean is not significantly lower than 75 at αα = 0.10, so there is statistically insignificant evidence to conclude that the population mean final exam score for students who are given colored pens at the beginning of class is equal to 75.
• The data suggest that the population mean final exam score for students who are given colored pens at the beginning of class is not significantly lower than 75 at αα = 0.10, so there is statistically insignificant evidence to conclude that the population mean final exam score for students who are given colored pens at the beginning of class is lower than 75.
• The data suggest the populaton mean is significantly lower than 75 at αα = 0.10, so there is statistically significant evidence to conclude that the population mean final exam score for students who are given colored pens at the beginning of class is lower than 75.

# The average final exam score f

The average final exam score for the statistics course is 81%. A professor wants to see if the average final exam score for students who are given colored pens on the first day of class is lower. The final exam scores for the 16 randomly selected students who were given the colored pens are shown below. Assume that the distribution of the population is normal.

84, 61, 80, 78, 75, 91, 90, 80, 63, 68, 82, 79, 88, 78, 68, 58

What can be concluded at the the x = 0.05 level of significance level of significance?

1. For this study, we should use a t-test for a population mean
2. The null and alternative hypotheses would be:

H0:  ?      _____

H1:  ?  _____

# The average final exam score f

The average final exam score for the statistics course is 74%. A professor wants to see if the average final exam score for students who are given colored pens on the first day of class is lower.

51, 86, 77, 86, 66, 59, 66, 76, 55, 59, 57, 80

What can be concluded at the α = 0.10 level of significance?

1. For this study, we should use Select an answer t-test for a population mean z-test for a population proportion

H1:H1:  ? p μ  Select an answer = > < ≠

# The average final exam score f

The average final exam score for the statistics course is 74%. A professor wants to see if the average final exam score for students who are given colored pens on the first day of class is different. The final exam scores for the 14 randomly selected students who were given the colored pens are shown below. Assume that the distribution of the population is normal.

71, 72, 53, 61, 75, 55, 75, 74, 58, 50, 71, 84, 76, 53
