Do people walk faster in an airport when they are departing (getting on a plane) or after they have arrived (getting off a plane)? An interested passenger watched a random sample of people departing and a random sample of people arriving and measured the walking speed (in feet per minute) of each. A hypothesis test is to be performed to determine if the mean walking speed is different between departing and arriving passengers at an airport. Suppose the p-value is 0.14. What is an appropriate conclusion? Choose the correct answer below. O A. There is sufficient evidence at the 5% significance level to indicate that the mean walking speeds for arriving and departing passengers are the same. B. There is not sufficient evidence at the 5% significance level to indicate that the mean walking speeds for arriving and departing passengers are different. C. There is not sufficient evidence at the 5% significance level to indicate that the mean walking speeds for arriving and departing passengers…
In recent years, approximately 55% of eligible voters take the time to vote in presidential elections. A poll based on a random sample of 200 eligible voters finds that 128 plan to vote in the next presidential election. Does this data provide convincing evidence at the ?α = 0.05 level that the proportion of eligible voters who will take time to vote in the next presidential election differs from 0.55?
Do question 7,8 and 9 only The new study also carried out a test to determine whether the population proportion of unvaccinated school children contracting winter flu was higher than the population proportion of vaccinated school children. The Z test statistic to test this belief is found to be 1.874. The corresponding p-value is 0.0305 0.1212 0.3036 0.7724 Question 7 Suppose that the new study uses a level of significance of 0.05 to test the claim in Question 6. The probability of Type I error is 0.025 0.05 0.95 0.975 Question 8 Based on previous studies of school children who were vaccinated and contracted the flu, the time in hours that the flu symptoms last is assumed to follow a normal distribution with a mean of 20.7 hours and a standard deviation of 7.3 hours. The probability that a randomly selected school child has flu symptoms for more than 24 hours is 0.1628 0.3256 0.6744 0.8372 Question 9 Suppose that a random sample of 5 vaccinated school children is taken.

Significance Testing Handout Name For each of the following scenarios, complete a thorough and complete test of significance. Be sure your write-ups include all of the following steps: 1. Define the parameter(s) of interest. 2. State in symbols and in words your null and alternative hypotheses. 3. Draw and label an appropriate diagram of the sampling distribution. 4. Check the technical conditions for this problem. Is your sampling distrubution valid? (For the sake of review, complete the problems regardless of whether or not the conditions hold!) 5. Determine the p-value for this application. 6. Explain what the p-value tells you about your sample result. Be sure to interpret this number as a probability. 7. State the results of your test keeping your comments within the context of the application. (This usually requires several sentences). 8. Have the…
A left-tailed z-test found a test statistic of z = -1.99. At a 5% level of significance, what would the correct decision be? Question 20 options: Do not reject H0 Do not reject H1 Accept H0 Reject H1 Reject H0
The value obtained for the test statistic, z, in a one-mean z-test is given. Also given is whether the test is two tailed, left tailed, or right tailed. Determine the P-value. Round to four decimal places, as needed. A left-tailed test: Z = -1.17

A report states the average temperature for the month of June on a specific tropical island is 98 degrees F. A meteorologist claims the report is not correct.. Data collected from 35 areas on the island showed an average temperature of 94 degrees F. Thepopulation standarddeviation is known to be 6.0 degrees F. At alpha = 0.05, can the report's average be rejected? For multiple choice question #1, tell what type of test: right-tailed, left-tailed, or two-tailed.
Suppose that having a widow's peak was a dominant trait (W) compared to not having a widow's peak (w). In a sample size of 30 students, 15 were observed to have a widow's peak and 15 did not have a widow's peak. The expected frequency of a widow's peak is 75% chance of getting it and a 25% chance of not getting it. Perform a chi square analysis to see if the data above agrees with the predicted outcome.
Suppose we are interested in investigating the mean of a normally distributed population. As part of the investigation, we intend to draw a sample of 1400 observations from this population and carry out a test of the null hypothesis Ho : µ =450 against a two-sided alternative hypothesis. Suppose that in reality, the population mean is 450. On average, what will the p-value equal? (Give your numeric response to at least 3 decimal places. Give only your numeric response, and not any extra characters or symbols.) Your Answer: Your Answer
