The average height of students in a freshman class of a certain school has been 165.83 cm with a population standard deviation of10.57 cm. Is there a reason to believe that there has been a change in the average height if a random sample of 50 students in thepresent freshman class has an average height of 168.18 cm? Use a 0.05 level of significance."No, there is no sufficient evidence to say that the height of the freshmen students changed based on empiricalevidence because the calculated z is not in the critical region.""Yes, there is sufficient evidence to believe that the height of the freshmen students changed based on empiricalevidence because the calculated z is not in the critical region.""No, there is no sufficient evidence to say that the height of the freshmen students changed based on empiricalevidence because the calculated z is in the critical region.""Yes, there is sufficient evidence to believe that the height of the freshmen students changed based on empiricalevidence because the calculated z is in the critical region."

Suppose that shoe sizes of American women have a bell-shaped distribution with a mean of 8.12 and a standard deviation of 1.53 Using the empirical rule, what percentage of American women have shoe sizes that are less than 9.65? Please do not round your answer.
Data were collected on annual personal time (in hours) taken by a random sample of 16 women (group1) and 7 men (group 2) employed by a medium sized company. The women took an average of 24.75 hours of personal time per year with a standard deviation of 2.84 hours. The men took an average of 21.89 hours of personal time per year with a standard deviation of 3.29 hours. The Human Resources Department believes that women tend to take more personal time than men because they tend to be the primary child care givers in the family. The results of the test are t = 2.00 with an associated P-value of 0.0367. The correct conclusion at a = 0.05 is to A. reject the null hypothesis. B. fail to reject the null hypothesis. C. conclude that women take a higher average number of hours of personal time per year compared to men. D. Both B and C. E. Both A and C. O A O O O B D ΟΕ
Is there strong evidence of global warming? Let’s consider a small scale example, comparing how temperatures have changed in the US from 1968 to 2008. The daily high temperature reading on January 1 was collected in 1968 and 2008 for 51 randomly selected locations in the continental US. Then the difference between the two readings (temperature in 2008 - temperature in 1968) was calculated for each of the 51 different locations. The average of these 51 values was 1.1 degrees with a standard deviation of 4.9 degrees. We are interested in determining whether these data provide strong evidence of temperature warming in the continental US. (d) Calculate the test statistic and find the p-value. (e) What do you conclude? Interpret your conclusion in context. (f) Calculate a 90% confidence interval for the average difference between the temperature measurements between 1968 and 2008. Interpret this interval in context. (g) Does the confidence interval provide convincing evidence that the…
Suppose the mean height of women age 20 years or older in a certain country is 62.2 inches. One hundred randomly selected women in a certain city had a mean height of 61.7 inches. At the 1% significance level, do the data provide sufficient evidence to conclude that the mean height of women in the city differs from the national mean? Assume that the population standard deviation of the heights of women in the city is 3.9 inches. Set up the hypotheses for the one-mean z-test.

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 comparison is made between two bus lines to determine if arrival times of their regular buses from Denver to Durango are off schedule by the same amount of time. For 51 randomly selected runs, bus line A was observed to be off schedule an average time of 53 minutes, with standard deviation 15 minutes. For 60 randomly selected runs, bus line B was observed to be off schedule an average of 60 minutes, with standard deviation 11 minutes. Do the data indicate a significant difference in average off-schedule times? Use a 5% level of significance.

A new computer chip design(A) is being compared to the current design(B).Fifty independent chips of each design are tested for speed at performing a certain task. The new computer chip (A) performed the task in 481.2 ms, on average, with a sample standard deviation of 14.3 ms. The current computer chip (B) performed the task in 495.6 ms, on average, with a sample standard deviation of 16.4 ms. Can you conclude, at a 5% significance level, that chip A performs this task faster than chip B?

A sample of 45 adult men from Lahug showed that the mean time they spend working from home is 28.50 hours per week with a standard deviation of 4 hours. Another sample of 40 adult men from Pardo showed that the mean time spent by them working from home is 23.25 hours per week with a standard deviation of 5 hours. Using a 2.5% significance level, can you conclude that the mean time spent working from home by adult men in Lahug is greater than that for adult men in Pardo? Assume that the standard deviations for the two populations are equal.

The mean age when smokers first start is 13 years old with a population standard deviation of 1.8 years. A researcher thinks that smoking age has significantly changed since the invention of ENDS-electronic nicotine delivery systems. A survey of smokers of this generation was done to see if the mean age has changed. The sample of 35 smokers found that their mean starting age was 12.3 years old. Do the data support the- claim at the 5% significance level? What are the correct hypotheses? Ho: Select an answer e years H1: Select an answer e years Based on the hypotheses, find the following: Test Statistic z = (Round to 4 decimal places.) Critical Values = = (Round to 2 decimal places.) Based on the above we choose to Select an answer O that the mean age smokers The correct summary would be: Select an answer first start is different than 13.
The BDHS reported that the mean cholesterol level in 2020 for all adults was 203 in a certain area. Around a sample of 3,310 participants were questioned about the cholesterol levels who attended the last month survey and it is found that mean cholesterol level is 200.3 with a standard deviation of 36.8. Is there any statistical evidence of a difference in mean cholesterol levels in that area? Conduct the test at 1% level of significance. a. Which of the following statistical tests is most appropriate in this scenario? Two-Tailed Z-Test One-Tailed Z-Test Two-Tailed T-Test One-Tailed T-Test b. What are the appropriate hypotheses for the test? Но : д — 203 Н : д + 203 Но : д + 203 Н] :д — 203 Но : и — 200.3 Ні : д > 200.3 Ho : µ = 200.3 H1 : µ < 200.3 C. After conducting the appropriate significance test, the test statistic was found to be -4.22. Therefore, the conclusion for the test is: Reject Ho, because p-value is less than 0.01 Fail to reject Ho, because -4.22 falls outside the…
