The blue catfish (Ictalurus Furcatus) is the largest species of North American catfish. The current world record stands at 143 pounds, which was caught in the John H. Kerr Reservoir (Bugg's Island Lake) located in Virginia. According to American Expedition, the average weight of a blue catfish is between 20 to 40 pounds. Given that the largest blue catfish ever caught was at the John H. Kerr Reservoir, you believe that the mean weight of the fish in this reservoir is greater than 40 pounds. Use the data below, which represents the summary statistics for 50 blue catfish caught at this reservoir, and a 0.05 significance level to test the claim that the mean weight of the fish in the John H. Kerr Reservoir is greater than 40 pounds. n=50 ;  ¯x=40.49 pounds;  s=3.49 pounds a) Identify the null and alternative hypotheses?

Mice can be a serious public health issue, as they can carry disease and parasites. It is important to track their feeding and living spaces. The accompanying data are a subset of data from a scatterplot that appeared in the paper "Small Mammal Responses to Fine Woody Debris and Forest Fuel Reduction in Southwest Oregon."+ The authors of the paper were interested in how the distance a deer mouse will travel for food is related to the distance from the food to the nearest pile of fine woody debris. Distances were measured in meters. Distance from Debris in Meters (x) 6.94 m 5.23 5.21 7.10 8.16 5.50 9.19 9.05 9.36 Distance Traveled in Meters (y) 0.00 6.13 11.29 14.35 12.03 22.72 20.11 26.16 30.65 The equation of the regression line is ŷ = -7.69 + 3.23x. How far (in m) would we predict a mouse to travel for food if the distance from a pile of debris is 7.49 m? (Round your answer to two decimal places.)

A study was done to identify variables that might produce high click counts on Twitter. You and 14 of your friends collect data on all of your tweets for a week. You record the number of click counts, the length of each tweet, the outside temperature, whether it is raining, the time of day, and the day of the week. Classify each of the variables as explanatory or response. click counts V[ Choose ] response explanatory length of each tweet Choose] outside temperature [ Choose ] raining [Choose ] time of day [Choose ) day of week [ Choose ] >

Suppose you as a researcher have collected data on wages, education, experiences and gender. In addition, you also asked the information on whether the respondent graduated from local or overseas university. Write a model that would allow you to test whether graduates from overseas university has different effect on wages between male and female. Describe the proxies and unit of measurement you use for the variables in the model.

A professor was interested in how the amount of sleep may impact a student’s performance in her course. She asked students to record the number of hours they sleep on a typical weeknight. The data can be found in the file hours_sleep.xlsx. You will need to use this information to respond to the questions belowDescribe the variability of this distribution (please be sure to include the appropriate statistics to support your description).
