# Analysis of Online Hours Based on Gender## IntroductionThis study investigates whether there is significant evidence at the 0.05 level of significance that the mean number of hours spent online per week is the same for both males and females on a specific social networking platform. It assumes unequal population variances between male and female groups.## Hypothesis Testing### Null Hypothesis (H₀)The mean number of hours spent online per week is the same for both males and females.\[ H_0: \mu_1 = \mu_2 \]### Alternative Hypothesis (H₁)The mean number of hours spent online per week is different for males and females.\[ H_1: \mu_1 \neq \mu_2 \]Here, population 1 refers to females and population 2 refers to males.## Steps to Compute1. **Compute the Test Statistic:** - Round to two decimal places.2. **Find the p-value:** - Round to three decimal places.3. **State the Conclusion:** - Compare the p-value to the chosen level of significance $\alpha$ = 0.05. - Determine whether to reject or fail to reject the null hypothesis. - Assess if there is evidence to conclude a difference in online hours between males and females.## Survey DataThe survey data table includes the gender and the number of hours spent online per week for each participant.| Gender | Hours Online/Week | Gender | Hours Online/Week ||--------|-------------------|--------|-------------------|| Female | 4 | Male | 7 || Female | 9 | Male | 15 || Female | 10 | Male | 6 || Female | 5 | Male | 4 || Female | 7 | Male | 6 || Female | 13 | Male | 3 || Female | 2 | Male | 9 || Female | 6 | Male | 4 || Female | 3 | Male | 6 || Female | 5 | Male | 8 || Female | 7 | Male | 5 || Female | 4 | Male | 4 || Female | 3 |

The mean purchase total is $93.80 and the median purchase total is $75.80. The store manager investigates and learns that the customer that made a $500 purchase had not purchased groceries, but rather a $500 gift card. Because this customer's purchase was not typical, the manager decides to exclude this total from the data set. How will removing the $500 purchase from the data set affect the value of the mean and the median?
The Economist collects data each year on the price of a Big Mac in various countries around the world. The price of a Big Mac for a sample of McDonalds restaurants in Europe in May 2009 resulted in the following Big Mac prices (after conversion to U.S. dollars):3.80 5.89 4.92 3.88 2.65 5.57 6.39 3.24The mean price of a Big Mac in the U.S. in May 2009 was $3.57. For purposes of this exercise, assume it is reasonable to regard the sample as representative of European McDonalds restaurants. Does the sample provide convincing evidence that the mean May 2009 price of a Big Mac in Europe is greater than the reported U.S. price? Test the relevant hypotheses using a = .05.

A psychologist has designed an index to measure the social perspectives of elementary school children. The index is based on ratings of a child’s responses to questions about a set of photographs showing different social situations. The following are the indices measured on a random sample of 16 children attending elementary school in a particular district. 48, 75, 69, 58, 60, 68, 59, 66, 71, 52, 49, 60, 54, 55, 70, 57 For the data the mean index is 60.69 and the standard deviation is 8.26.

Secretary of State Roxana Tillerson is worried about malpractice at the 4 processing centers for Green Cards in the country. Green Card applications are given a grade g on a scale 0-100. They are assigned randomly to different centers and thus Tillerson expects all centers to have similar mean scores. She collects the data in the table. #applications 9360 67.27 15.29 1 9870 66.74 14.64 7020 66.94 15.14 3 5040 67.02 14.84 4 rows x 3 columns At this point she just wants to decide whether or not to initiate a deeper investigation into malpractice at all sites.
