Historically, the time spent by DCSI3710 students on trying to certify any HLS homework is known to have a mean of 35 minutes. In order to examine the claim that homework 12.2 was actually more time-consuming, an instructor asked 16 students how much time they spent on it. Assume that the p-value associated with the test statistic is 0.03. At a significance level of 0.01, what is the conclusion of the hypothesis test?
A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 223 vinyl gloves, 57% leaked viruses. Among 223 latex gloves, 5 leaked viruses. Using the accompanying display of the technology results, and using a 0.01 significance level, test the claim that vinyl gloves have a greater virus leak rate than latex gloves. Let vinyl gloves be population 1. H^0: p^1=p^2 H^1: p^1>p^2 Identify the test statistic: (round to two decimal places)
A random sample of 40 companies with assets over $10 million was surveyed and asked to indicate their industry and annual computer technology expense. The ANOVA comparing the average computer technology expenses among three industries rejected the null hypothesis. The mean square error (MSE) was 211. The following table summarizes the results: Education Tax Services Food Services Number Sampled 10 14 16 Mean Expense (1,000,000s) 18 47.5 52 When comparing the mean annual computer technology expenses for companies in the tax services and education industries, which of the following 95% confidence intervals can be constructed? Multiple Choice 29.5 ± 2.026 × 6.014 29.5 ± 2.021 × 6.014 29.5 ± 2.026 × 29.96 29.5 ± 2.021 × 29.9
A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 228228 vinyl gloves, 6767% leaked viruses. Among 228228 latex gloves, 55% leaked viruses. Using the accompanying display of the technology results, and using a 0.050.05 significance level, test the claim that vinyl gloves have a greater virus leak rate than latex gloves. Let vinyl gloves be population 1.
The Excel file Room Inspection provides data for 100 room inspections at 25 hotels in a major chain. Management would like the proportion of nonconforming rooms to be less than 2%. Test an appropriate hypothesis to determine if management can make this claim.

In a study of 420,052 cell phone users, 131 subjects developed cancer of the brain or nervous system. Test the claim of a somewhat common belief that such cancers are affected by cell phone use. That is, test the claim that cell phone users develop cancer of the brain or nervous system at a rate that is different from the rate of 0.0340% for people who do not use cell phones. Because this issue has such great importance, use a 0.005 significance level. Identify the null hypothesis, alternative hypothesis, test statistic, and P-value. Use the P-value method and the normal distribution as an approximation to the binomial distribution.
A researcher is conducting a study on payment of property rate based on 255 randomly selected houses in a district. The table below, which is extracted from the researcher’s dataset, shows the ages of the houses (measured as “New”, “Quite New”, “Old”, “Very New”) and whether the owners of those houses pay property rate to the District Assembly. Using an alpha level of 5%, conduct a Chi-Squared test to establish whether there is a significant association between the age of the house and the payment of property rate.
In a study of 420,055 cell phone users, 107 subjects developed cancer of the brain or nervous system. Test the claim of a somewhat common belief that such cancers are affected by cell phone use. That is, test the claim that cell phone users develop cancer of the brain or nervous system at a rate that is different from the rate of 0.0340% for people who do not use cell phones. Because this issue has such great importance, use a 0.005 significance level. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method and the normal distribution as an approximation to the binomial distribution.
A random sample of 40 companies with assets over $10 million was surveyed and asked to indicate their industry and annual computer technology expense. The ANOVA comparing the average computer technology expenses among three industries rejected the null hypothesis. The mean square error (MSE) was 209.

Select one: a. 27.5 ± 2.021 × 5.986 b. 27.5 ± 2.026 × 27.96 c. 27.5 ± 2.021 × 27.9 d. 27.5 ± 2.026 × 5.986
A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 254 vinyl gloves, 60 % leaked viruses. Among 254 latex gloves, 14 % leaked viruses. Using the accompanying display of the technology results, and using a 0.01 significance level, test the claim that vinyl gloves have a greater virus leak rate than latex gloves. Let vinyl gloves be population 1. Identify the test statistic and the pvalue
A researcher was interested in comparing the resting pulse rates of people who exercise regularly and of those who do not exercise regularly. Independent simple random samples of 16 people who do not exercise regularly and 12 people who exerciseregularly were selected, and the resting pulse rates (in beats per minute) were recorded. The summary statistics are as follows. Use a 0.025 significance level to test the claim that the mean resting pulse rate of people who do not exercise regularly is larger than the mean resting pulse rate of people who exercise regularly. a)Identify the null hypothesis, alternative hypothesis. b)Find the test statistics c)Find the critical value d)Conclusion about the null hypothesis e)State the conclusion
A company makes a device that can be fitted to car engines to improve their fuel efficiency. The company asserts that when the device is installed drivers should experience a mean increase of more than 3kilometres per litre. Assuming that the population standard deviation of increase is known to be 0.75kilomtres per litre and a sample size of 64 cars is selected with a mean of 3.25kilometres per litre, use the p-value approach to test the null hypothesis using a significance level of 0.05.
