A one-sample t‐test is conducted on H 0 : Population mean = 81.6. H a : Population mean > 81.6. In a simple random sample of 15,  the test statistic was -1.8. The p-value is: 

A farmer suspects that their chickens are lighter than average for the chickens’ breed. The breed is supposed to weigh 6 pounds after 10 weeks. The farmer takes a random sample of 16 chickens from their brood, the mean of the sample is 5.6 pounds and the standard deviation of the sample is 0.8 pounds. Based on previous information it is known that the distribution of weight (pounds) in the population is close to normal.   What is the appropriate test to apply to support the farmer’s suspicion?    

What is the probability of a standard normal variable having a value between 0.5 and 2.5? Report your answer in decimal format with four decimal places, for example “0.1234”.  

A track coach claims that their new month-long training program will reduce the mile time by more than 1 minute. You want to statistically test the coach’s claim. You decide to randomly select 5 runners and record their mile times. You then have them follow the coach’s training program for a month and record their mile times post-training program. The times are listed below.   Subject Mile time Before Training Mile time After Training 1 6.7 5.0 2 7 5.8 3 6.2 4.9 4 8.5 7.2 5 9 7.6     This data could be appropriately analyzed using [color1],   We are interested in the hypotheses: [color2]. The degrees of freedom are [color3]  

Animal behavior researchers are interested in investigating if there is association between pet type and toy color. 229 pets were randomly selected out of a large population of cats and dogs. They asked these pets to choose a toy. Four different colors were available: red, blue, yellow, and green. The number of dogs and cats who selected each color is shown in the table below.  Red Blue Yellow Green Dogs 48 24 18 30 Cats 55 34 2 18 A Chi square test for independence was used to test the researchers claim.  Select the correct answer.

The distribution we use to find the p-value assumes…      

Eric wants to investigate the relationship between the number of tomatoes a plant produces and the number of aphids he finds on the plant. He takes a sample of five plants from his garden at random and gathers  the following data: Plant Number of tomatoes Number of Aphids 1 5 13 2 8 11 3 6 7 4 11 5 5 18 2 It appears that a straight line seems like a reasonable model for this data.  Note the following information: The mean number of aphids is 9.6. The SD of the number of aphids is 5.2 The mean number of tomatoes  is 7.6. The SD of the number of tomatoes is 4.4. The correlation between the number of aphids and the number of tomatoes is -0.85. a) Calculate the slope and intercept for a linear regression model with number of tomatoes as the response variable (2 points). b) Predict the number of tomatoes on a plant with 12 aphids  (2 points).
