In a sample of 200 male students, 130 said they exercise regularly. In a sample of 300 female students, 180 said they exercise regularly. Test the claim that male students exercise more regularly than female students, at the alpha = 0.05 significance level. Let the population of men be labeled M and the population of women be labeled W.
Hypothesis Test: Information: Test Statistic: Z = 1.728 p-value = 0.123 A. Use the p-value approach to complete the hypothesis test. B. What are your decision and conclusion in words? |

(6 pts) A psychologist who needs two groups of
students for a learning experiment decides to select a random
sample of female college
students and male college students. Before the experiment, the
psychologist administers an IQ test to both groups to determine if
there is a significant difference in their mean IQ scores. The
population standard deviation for this IQ test is know to be
for both female and male populations. If the sample
mean IQ score of the female...

A researcher claimed that a higher proportion of women than men exercise regularly. A random sample of 150 men found that 88 of the men exercise regularly, while a random sample of 200 women found that 130 of the women exercise regularly. Test this claim using a significance level of 0.01. What is the z-stat? What is the p-value? What is your decision for the hypothesis test above? Retain or reject Ho? Please write a statement that summarizes your findings...

9. A De Anza statistics instructor wonders about the performance of male and female college students in her statistics class. She wants to know whether there is a difference between final exam scores of male and female students. From all of the statistics classes she has taught in the last two years, she randomly selected scores of 63 female students and 58 male students. The females had a sample mean score of 78 with a standard deviation of 6. The...

In 1935, 25.3% of college students enrolled in an education major were male. A sample of students enrolled in an education major in 1995 consisted of 115 females and 65 males. Would this data be sufficient at the 0.05 level of significance to conclude that the percentage of males enrolled in an education major increased from the 25.3%? Use the P-Value Method of Testing. In your work space below, you will need to have - 1. The null hypothesis, Ho...

The Mean ACT score for 43 male high school students is 21.1 with a standard deviation of 5.0. The mean ACT score for 56 female high school students was 20.9 with a standard deviation of 4.7. Test the claim that male and female students have equal test scores. Test at a level of significance of 0.01 Make sure you give an answer for each of the following: a) Claim in symbols and labeled Ho or Ha and labeled as the...

The market researchers at Barton’s pizza are interested in the proportion of male customers and female customers that would be willing to try a new pizza. Random samples of 176 males and 124 females were randomly selected. Responses were recorded as Yes (i.e. interested) or No (i.e. not interested) and are listed as variables MalesInterested (1) and FemalesInterested (2). The samples indicated that 91 males and 59 females respectively were interested in trying a new pizza. Test that the proportion...
