A company produces packages of A company produces packages of granola and has changed its recipe. It claims that theproportion of almonds in the new recipe is greater than in the previous recipe.In order to test this claim, you take a 100-gram sample from the old recipe and a 100-gramsample from the new recipe. The old recipe sample contains 29 grams of almonds, while thenew recipe sample contains 42 grams of almonds.When you test the claim that the proportion of almonds in the new recipe is greater than in theprevious recipe, what is the P-value and the conclusion at a significance level of 0.05?OP-value = 0.026251; fail to reject the null hypothesis that there is no difference in the proportionsⒸP-value = 0.052501; fail to reject the null hypothesis that there is no difference in the proportionsⒸP-value = 0.026251; reject the null hypothesis that there is no difference in the proportionsOP-value = 0.052501: reject the null hypothesis that there is no difference in the proportions

After receiving complaints from McDonald’s customers in Japan about the amount offrench fries being served, the on-line news magazine ”Rocket News” decided to testthe actual weight of the fries served at a particular Japanese McDonald’s restaurant.According to the Rocket News article, the official weight standard set by McDonald’s ofJapan is for a medium sized fries to weigh 135 grams. The publication weighed the friesfrom 36 different medium fries they purchased and found the average weight of the friesin their sample to be 130 grams with a variance of 225 grams. Research Question: Doesthe data suggest that the medium fries from this McDonald’s in Japan are underpacked?Useα=0.05. (a) Which of the following is theH0?

In a study at The Ohio State University, 16 student volunteers drank a randomly assigned number of cans of beer. Thirty minutes later, a police officer measured their blood alcohol content (BAC) in grams of alcohol per deciliter of blood. Throughout the United States, the legal BAC limit is 0.08. The students were equally divided between men and women and differed in weight and usual drinking habits. Because of this variation, many students do not believe that the number of ingested drinks predicts BAC well.The data in the given figure consists of: a.2 unpaired sets of values, each of which has 16 values b.32 ordered pairs of values c.16 ordered pairs of values
(b) After receiving complaints from McDonald’s customers in Japan about the amount of french fries being served, the on-line news magazine ”Rocket News” decided to test the actual of the fries served at a particular Japanese McDonald’s restaurant. According to the Rocket News article, the official weight standard set by McDonald’s of Japan is for a medium sized fries to weigh 120 grams. The publication weighed the fries from 25 different medium fries they purchased and found the average weight of the fries in their sample to be 115 grams with variance of 100 grams. Research Question: Does the data suggest that the medium fries from this McDonald’s in Japan are underpacked? Use α =0.05. I computed TS correctly and it is Z = -2.5. Based upon the guidelines in 9.5, this TS leads to reject H0 . Now suppose I change α = 0.01, does the conclusion lead to accept H0 ?

A local college cafeteria has a self-service soft ice cream machine. The cafeteria provides bowls that can hold up to 16 ounces of ice cream. The food service manager is interested in comparing the average amount of ice cream dispensed by male students to the average amount dispensed by female students. A measurement device was placed on the ice cream machine to determine the amounts dispensed. Random samples of 85 male and 78 female students who got ice cream were selected. The sample averages were 7.23 and 6.49 ounces for the male and female students, respectively. Assume that the population standard deviations are 1.22 and 1.17 ounces, respectively. Using the 1% significance level, can you conclude that the average amount of ice cream dispensed by male college students is larger than the average amount dispensed by female college students? What is the type of test to be used?
High cholesterol is one of the major risk factors for heart disease. A total cholesterol reading above 190 mg/dL is considered high.A physician is concerned that a patient may be at risk for high cholesterol. In order to accurately measure the patient's average cholesterol level, the physician instructs the patient to come into the physician's office once a week for 12 weeks for a blood lipid screening. The results of the 12 measurements are listed below. 189 186 199 197 190 186 185 200 200 200 185 190 Use the critical value method to test the hypothesis that the patient's cholesterol level is greater than 190 mg/dL, using a significance level of 10%. Assume that the distribution of all cholesterol measurements from this patient is approximately normally distributed. Determine the critical value(s) for this hypothesis test. Round the solution(s) to four decimal places. If more than one critical value exists, enter the solutions using a comma-separated list.Determine the test…
