Suppose that the average trip time from Oak Park to UIC on the Blue line is 25 minutes and that the standard deviation of the population is 16 minutes (sigma=16). We are interested to know whether the average trip time on Thursdays is shorter. We study a sample of 49 trips on Thursdays and the average is 24.25 minutes. Execute a hypothesis test at alpha=10% that the average trip time on Thursdays is shorter (that is, that it requires a smaller number of minutes). State Ho, Ha, calculate the appropriate statistic, p-value, state whether you reject Ho vs. not and state your conclusion in plain English. What is the largest number of minutes that will allow you to reject Ho? What is the probability that you will reject Ho if mu is actually 24 minutes? Fill in the probabilities in the table below. Also indicate alpha, beta and power. What test concludes Ho is true in population Ho not true in population Reject Ho Not reject Ho

An independent consumer group published its finding that the lifetimes of electric bulbs manufactured by BIG Corporation are approximately normally distributed with a mean of 690days and a standard deviation of 120.5. BIG Corporation claims that the standard deviation of its electric bulbs is less than 120.5. Suppose that we want to carry out a hypothesis test to see if BIG Corporation's claim is correct. State the null hypothesis H0 and the alternative hypothesis H1 that we would use for this test. Ho ___ H1 ___
An appliance manufacturer claims to have developed a compact microwave oven that consumes a mean of no more than 250 W. From previous studies, it is believed that power consumption for microwave ovens is normally distributed with a population standard deviation of 15 W. A consumer group has decided to try to discover if the claim appears true. They take a sample of 20 microwave ovens and find that they consume a mean of 257.3 W. The appropriate hypotheses to determine if the manufacturer's claim appears reasonable are Question 18 options: 1) H0 : μ ≤ 250 versus H1 : μ > 250. 2) H0 : μ ≥ 257.3 versus H1 : μ < 257.3. 3) H0 : μ = 250 versus H1 : μ ≠ 250. 4) H0 : μ ≥ 250 versus H1 : μ < 250.
Eighteen undergraduate students were randomly selected from a university and their systolic blood pressure was tested. The sample mean and standard deviation were 126.4 mmHg and 11.0 mmHg respectively. What is the obtained t-score for this sample under the null hypothesis Ho: µ = 118?
A random sample of 225 nails in a manufacturing company is gathered. The engineer specified length of a nail must be 8 centimeters having a standard deviation of 0.04 centimeters. It shows that the average weight of the nails is 8.055 centimeters. Do the produced nails exceed the specification of the engineer at a 1% level of significance. 1. What is the null hypothesis of the problem? 2. What is the alternative hypothesis of the problem and what is the direction of the alternative hypothesis?
Suppose there are two different vaccines for Covid, Vaccine X and Vaccine Y. An interesting question is which vaccine has a higher 6-month antibody effectiveness quotient (6AEQ). To examine this we randomly select 75 recipients of vaccine X and 83 recipients of vaccine Y. The vaccine X recipients had a mean 6AEQ of x = 129. The vaccine Y recipients had a mean 6AEQ of y = 133. It is recognized that the true standard deviation of 6AEQ for vaccine X recipients is a = 9.7 while it is recognized that the true standard deviation of 6AEQ for vaccine Y recipients is σy = 10.7. The true (unknown) mean 6AEQ for vaccine X recipients is x, while the true (unknown) mean 6AEQ for vaccine Y recipients is My. 6AEQ measurements are known to be a normally distributed. In summary: Type Sample Size Sample Mean Standard Deviation Vaccine X 75 129 Vaccine Y 83 133 9.7 10.7 a)Calculate the variance of the random variable X which is the mean of the 6AEQ measurements of the 75 vaccine X recipients. b)Calculate…
A pharmaceutical company claims that they have a new drug that will significantly reduce the average recovery time for a particular operation. Until now the mean recovery time has been 21.7 hours. The next 22 patients having this operation at a large teaching hospital are treated with the new drug and the average recovery time for these patients is found to be 20.3 hours with a standard deviation of 3.47 hours. Do the data support the pharmaceutical company's claim? Test the appropriate hypothesis at a = 0.10. (a). The null and alternative hypotheses are Но: р — 21.7 Ha: µ > 21.7 O Ho : µ = 20.3 На:д < 20.3 Но: р — 21.7 На:и < 21.7 O Ho : = 20.3 Ha:ã < 20.3

"An electrical firm produces light bulbs that have a length of life that is approximately normally distributed with a mean of 660 hours and a population standard deviation of 23 hours. A new version of light bulbs is being produced and is assumed to be better than the previous version. To test this claim, a random sample of 88 new light bulbs are tested. Would you buy the new version of the light bulb or would you buy the older version if the random sample showed an average of 750 hours? Use a 0.05 level of significance." I will certainly buy the older version because I am 100% sure it is better. I will buy the older version until there is sufficient evidence to do otherwise. I will buy the new version. There is no sufficient data to make a sound conclusion.
At a water bottling facility, a technician is testing a bottle filling machine that is supposed to deliver 500 ml of water, and in the past the standard deviation of the population of bottles has be 7.5 ml. The technician dispenses 39 samples of water and determines the volumes have a mean of 498.3 ml. The technician wants to perform a hypothesis test at (alpha) = 0.05 level to determine whether the machine is not dispensing 500 ml, and is thus out of calibration. Hypothesis Statement: Test Value(s): So, we ____ the null hypothesis because ______. There ______ enough evidence to support the claim that the machine mean volume differs from 500 ml and is out of calibration.
In CDMX, the population average of the age of pregnant women is 19 years. A sociologist believes that in the city where she lives the average is higher. For this, she selected 72 pregnant women, obtaining a mean of 20.7 years with a standard deviation of 6.3 years. We want to test the research hypothesis with a significance level of 0.05.

The average person can predict the suit of a card from a deck of cards on average 25% of the time. If a group of psychics predicted the suit of a card at the average rate of 27% accuracy (and a sample standard deviation of 10%), do they predict the suit of cards significantly (alpha = 0.05) more accurately than the average person?
