The mean length u of male geckos is 9.5 inches. A researcher studying a population of geckos in a certain region will conduct a hypothesis test to investigate whether there is evidence that the mean length is greater than 9.5 inches. A random sample of geckos was selected, and the sample mean i was calculated as 10 inches. Which of the following is the correct set of hypotheses? Họ : = 10 Ha : 5 + 10 A Ho : = 10 Ha : 5 < 10 B Ho : µ = 9.5 Ha : µ> 9.5 Họ : 4 = 9.5 На : д<9.5 D Họ : µ = 9.5 Ha : 4 + 9.5 E

The sales manager of a food company wants to determine if the weekly sales of 16 ounce packages of frozen broccoli has increased since last year. The mean weekly number of sales per store was 2,400 packages last year. The sales manager set the following hypotheses to test Hol=2400 H₁:H>2400 Available sales data are from 400 stores. Assume that this data set is a random sample. The sample mean is 2,430 and the sample standard deviation is 800. For the significance level of 5%, find the critical value. a) 2478.4 b) 2430 Oc) 2321.6 d) 2334.4 e) 2465.6
A USA Today article claims that the proportion of people who believe global warming is a serious issue is 0.63, but given the number of people you've talked to about this same issue, you believe it is less than 0.63. The hypotheses for this test are Null Hypothesis: p ≥ 0.63, Alternative Hypothesis: p < 0.63. If you randomly sample 20 people and 12 of them believe that global warming is a serious issue, what is your test statistic and p-value? Question 3 options: 1) Test Statistic: 0.278, P-Value: 0.391 2) Test Statistic: 0.278, P-Value: 0.609 3) Test Statistic: -0.278, P-Value: 0.782 4) Test Statistic: -0.278, P-Value: 0.391 5) Test Statistic: -0.278, P-Value: 0.609

There is a common belief that "men marry women who are younger than they are". To test this hypothesis, a random sample of 100 married couples were selected, and the ages of both the husband and wife were recorded. What is the name of the hypothesis test we would use to test that the mean age of men is higher than that of the women they marry? a) Two tailed Paired Samples t-test b) One tailed Paired Samples t-test c) Two Tailed Independent Samples t-test d) One Tailed Independent Samples t-test
Suppose you are asked to conduct a two-tailed hypothesis test on the population mean. What type of hypothesis test would you use? Why? What assumptions do you need to make about the process when you are conducting a hypothesis test on the population mean in order for your results to be valid?
Following an oil spill, a particular region of the ocean is being tested for the level of a chemical called naphthalene. It is considered fact that fish from the region will be safe to eat if, and only if, the mean naphthalene level in the region is less than 3.3 parts per billion. A set of water specimens will be randomly selected from the region and tested, and if the results provide convinving evidence that the mean naphthalene level is less than 3.3, then the sale of fish from the region will be made legal. Which of the following describes a Type I error and its consequences? A) the authorities fail to obtain convincing evidence that the mean naphthalene level is less than 3.3, and do not legalize the sale of fish from the region when in fact the fish are SAFE for consumption. B) The definition of a Type I error depends on the actual results of the study in question C) The authorities fail to obtain convincing evidence that the mean naphthalene level is less than 3.3, and do not…
