The Fish and Game Department stocked Lake Lulu with fish in the following proportions: 31% catfish, 14% bass, 41% bluegill, and 14% pike. Five years later it sampled the lake to see if the distribution of fish had changed. It found that the 503 fishes in the sample were distributed as follows Type of fish Observed caught catfish 120 bass 86 bluegill 221 pike 76 A) The sample has degree of freedom: ��=  B) The expected count of catfish category is: �=  C) Accurate to 2 decimal places, the component value of catfish category is: component=

Imagine a researcher asks a sample of five people to drive two types of cars and rate each of them on a scale of 1 to 25. The researcher wants to know: Is there is a difference in the ratings of the two types of cars. Below are the data collected: Type A: 20, 10, 11, 23, 7 Type B: 10, 11, 4, 12, 1 what type of T Test would be appropriate

Thirty randomly selected students were asked how many self- help books they have read in the last three years. Their responses are in the following frequency table.

A class of students each took a sample of 25 reeses pieces. These are their results: Orange     Yellow     Brown 17              7              7 15              8               2 11               7              7 7                  8            10 14                4              7 13                7               5 15                 4              6 11                  6              8 13                 7                5 7                    4             14 14                   4             7 Take a guess concerning the population proportion of orange candies. Is this the same as the proportion of orange candies from your original sample? Why or why not? Your origional sample is: Orange       Yellow       Brown 13                 7                5 j) Create a 95% confidence interval for the population proportion of orange candies.Point estimate: ? from the class data Critical z value: Standard error:Margin of Error: Lower Bound:Upper Bound:Interpretation:k) Did your guess in…
