It is believed that the average height of General Engineering (GE) students is 1.72 meters, which is 0.07 meters higher than Development Communication (DC) students with standard deviations of 0.34 meters and 0.30 meters respectively. An instructor verified this fact by obtaining 49 GE students and 36 DC students, having the average height of 1.75 meters and 1.66 meters. Is there an evidence that the instructor can circumvent the fact at 5% level of significance? 1. What is the null hypothesis of the problem? 2. What is the alternative hypothesis of the problem?

An experiment was conducted to a sample of nine gold fish and ten clown fish to determine if there is a significant difference in the average number of days that the fish can survive without food inside the aquarium. The gold fish averaged 11 days with a standard deviation of 2 days while the clown fish averaged 12 days with a standard deviation of 3 days. What is the appropriate alternative hypothesis?
A professional skier was trying to decide whether to use a new racing wax for cross-countryskis. He decided that the wax would be worth the price if he could average less than 55seconds to ski a course he knew well, so he planned to test the wax by racing on the course 8times. His sample of race times found a mean of 53.1 seconds, and standard deviation 7.0seconds. Is this sufficient evidence he should he buy the wax? Test at a .10 significancelevel.
The breaking strengths of cables produced by a certain manufacturer have historically had a mean of 1775 pounds and a standard deviation of 60 pounds. The company believes that, due to an improvement in the manufacturing process, the mean breaking strength, μ, of the cables is now greater than 1775 pounds. To see if this is the case, 90 newly manufactured cables are randomly chosen and tested, and their mean breaking strength is found to be 1788 pounds. Can we support, at the 0.05level of significance, the claim that the population mean breaking strength of the newly-manufactured cables is greater than 1775 pounds? Assume that the population standard deviation has not changed. Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places, and round your responses as specified below. a. State the null hypothesis H0 and the alternative hyposthesis H1. b. Find the value of the test statistic. c. Find the p-value. d. Can we…
The heights of women are normally distributed with a mean of 63.6 inches and a standard deviation of 2.5 inches. (show all work) To be considered extremely tall, a woman’s height must fall in the top 2% for all heights of women. What is the benchmark height for this designation? To be considered extremely short, a woman’s height must fall in the bottom 2% for all heights of women. What is the benchmark height for this designation?
Bone mineral density (BMD) is a measure of bone strength. Studies show that BMD declines after age 45. The impact of exercise may increase BMD. A random sample of 59 women between the ages of 41 and 45 with no major health problems were studied. The women were classified into one of two groups based upon their level of exercise activity: walking women and sedentary women. The 39 women who walked regularly had a mean BMD of 5.96 with a standard deviation of 1.22. The 20 women who are sedentary had a mean BMD of 4.41 with a standard deviation of 1.02. Which of the following inference procedures could be used to estimate the difference in the mean BMD for these two types of women

The honors program at Brad's university only accepts students with an entrance exam score over 400. What percentage of students would be eligible if the students at Brad's school have an average exam score of 250, with a standard deviation of 80?
Your research group has been hired to determine if college men and women drink different amounts of soft drinks at Illinois State University. After a careful study, your group has determined that males drink an average of 12 sodas per week with a standard deviation of 3.5 whereas female students drink an average of 9 soft drinks per week with a standard deviation of 2 sodas. The sample size of males is 200 and the sample size of females is 200. Based on this information, your group calculates the z-score to be: [____].
A psychologist investigated whether there is a difference, on average, in IQ scores for twins. She randomly selected 30 sets of twins from a database and measured their IQs. The mean difference (firstborn – second-born) was 2.1 points with a standard deviation of 7.2 points. Do the data provide a convincing evidence of a difference, on average, in IQ scores for twins? Do Perform the calculations, then complete the conclusion. Conclude Because the P-value, which is , is = 0.05, we H0. We convincing evidence of , on average, in IQ scores for twins.
A blood bank is conducting a study on how much time is required of their patients for blood platelet donations. Based on past records, time spent in the waiting room has a mean of 5 minutes and a standard deviation of 1 minute, time spent with a nurse who reviews patients' medical records and measures their vital signs has a mean of 10 minutes and a standard deviation of 3 minutes, and the actual donation time has a mean of 130 minutes and a standard deviation of 8 minutes. Assuming these three times are independent and can all be modeled using a normal distribution, approximately what proportion of donors finish the entire donation process in under 2.5 hours (150 minutes)? (A) 0.66 (B) 0.72 (C) 0.84 (D) 0.89 (E) 0.99
According to the norms established for a history test, Grade 8 students should have an average of 81.7 with standard deviation of 8.5. If 100 randomly selected grade 8 students from a certain school district average 79.6 in this test, can we conclude that at 0.05 level of significance that Grade 8 students from this school district can be expected to have a different average than the norm of 81.7?
The breaking strengths of cables produced by a certain manufacturer have historically had a mean of 1825 pounds and a standard deviation of 70 pounds. The company believes that, due to an improvement in the manufacturing process, the mean breaking strength, μ, of the cables is now greater than 1825 pounds. To see if this is the case, 17 newly manufactured cables are randomly chosen and tested, and their mean breaking strength is found to be 1844 pounds. Assume that the population is normally distributed. Can we support, at the 0.05 level of significance, the claim that the population mean breaking strength of the newly-manufactured cables is greater than 1825 pounds? Assume that the population standard deviation has not changed. Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places, and round your responses as specified below. (If necessary, consult a list of formulas.) (a) State the null hypothesis H0…
