A researcher wishes to determine if students are able to complete a certain puzzle more quickly while listening to music. Suppose the mean time to complete this puzzle without listening to music is 30 seconds with a standard deviation of 4 seconds. The researcher has 10,000 randomly selected college students complete the puzzle while listening to music. The mean time for these students is 79.8 seconds. The researcher conducts the following hypothesis test: Ho: = 80 vs. Hap< 80 and calculates a P-value that is less than 0.0001. It is appropriate to conclude which of the following? O With such a large sample size, statistically significant differences may not be of any practical Importance. O The researcher has strong evidence that, for college students, listening to music substantially improves the time to complete the puzzle. O The researcher has proved that for college students, listening to music substantially improves the time to complete a puzzle. O All college students should definitely listen to music when completing the puzzle.

Do political science classes require less writing than history classes? The 43 randomly selected political science classes assigned an average of 14.6 pages of essay writing for the course. The standard deviation for these 43 classes was 5.9 pages. The 52 randomly selected history classes assigned an average of 15.4 pages of essay writing for the course. The standard deviation for these 52 classes was 4.5 pages. What can be concluded at the a= 0.01 level of significance? For this study, we should use t-test for the difference between two independent population means a. The null and alternative hypotheses would be: Ho: 1 H₁: 1 C O μ2 C Add Work μ2 b.

It currently takes users a mean of 26 minutes to install the most popular computer program made by RodeTech, a software design company. After changes have been made to the program, the company executives want to know if the new mean is now different from 26 minutes so that they can change their advertising accordingly. A simple random sample of 51 new customers are asked to time how long it takes for them to install the software. The sample mean is 24.9 minutes with a standard deviation of 2.7 minutes. Perform a hypothesis test at the 0.025 level of significance to see if the mean installation time has changed. Step 3 of 3 : Draw a conclusion and interpret the decision.
An energy study found that household use of electricity had a mean of 682 and a standard deviation of 551 kilowatt-hours. Suppose the distribution of energy use was normal. Using a table, calculator, or software that can give normal probabilities, find the proportion of households with electricity use greater than 1000 kilowatt-hours.
It currently takes users a mean of 12 minutes to install the most popular computer program made by RodeTech, a software design company. After changes have been made to the program, the company executives want to know if the new mean is now different from 12 minutes so that they can change their advertising accordingly. A simple random sample of 91 new customers are asked to time how long it takes for them to install the software. The sample mean is 11.7 minutes with a standard deviation of 1.6 minutes. Perform a hypothesis test at the 0.05 level of significance to see if the mean installation time has changed. Step 2 of 3 : Compute the value of the test statistic. Round your answer to three decimal places.
A new species of dragonfly has an approximate body length of 45 mm with a standard deviation of 3 mm. In a sample of 40 dragonflies, what is the probability that the sample mean of the body length of the sample is between 44.5 and 45.5?
Seventy million pounds of trout are grown in the U.S. every year. Farm-raised trout contain an average of 32 grams of fat per pound, with a standard deviation of 8 grams of fat per pound. A random sample of 38 farm-raised trout is selected. The mean fat content for the sample is 29.7 grams per pound. Find the probability of observing a sample mean of 29.7 grams of fat per pound or less in a random sample of 38 farm-raised trout. Carry your intermediate computations to at least four decimal places. Round your answer to at least three decimal places.
Researchers asked two groups of people to construct a jigsaw puzzle. One group of 55 people, who listened to soft classical music while working, had a mean construction time of 45 minutes. Another group of 45 people, who worked in silence, had a mean construction time of 55 minutes. Assume the population standard deviations for the construction times for people listening to classical music and people working in silence are 9.5 minutes and 11 minutes, respectively. Find the upper bound of the 99% confidence interval for the difference in population construction times between people listening to classical music as they work and people working in silence. Let the people listening to classical music be the first sample, and let the people working in silence be the second sample. Assume the samples are random and independent. Assume that both the population distributions are normally distributed. Round your answer to two decimal places. 90% confidence=1.645 95% confidence=1.96…

The survey was given to 50 people. The mean score is 4.1 with a standard deviation of 2.6. We want to know if the data provide evidence that the mean score in the population is lower than 5. We will use alpha = 0.05 to make our decision. What is the null hypothesis for this question? Group of answer choices a. The proportion of people who pass the test is 5. b. The mean test score of the population is 5. c. The mean test score of the 50 people who took the test is 5. d.The standard deviation is 2.6
