Given the following data, determine the Chi-Square obtained statistic:

The following data set is of the average (just treat this as a regular data set...do not over think the fact that this is a data set of averages) number of three-point shots Stephen Curry made each season of his career: 2.1 2 2.1 3.5 3.3 3.6 5.1 4.1 4.2 5.1 2.4 5.3 5.4   What is the z-score of 2.4?       a. None of these   b. -1.06   c. 1.06   d. -0.96   e. 0.96

1)Dataset: 88 123 47 45 66 190 157 91 2) Using the dataset from Question #1, what is the median (Round your answer to the one decimal place)?

Find the correlation coefficient, r, for the sample data below (please round yourfinal answer to 3 digits after the decimal): x y 2 4 3 3 4 4 5 1 6 2

Given the population mean ? = 51 , population ???????? ????????? ? = 4 and a data set below find the z score only for 19 from the list. Data set: 12, 13, 19, 9, 4   Type the answer in hundredths places.

Forty students took a 50 point computer science test. The scores are shown in the stem and leaf plot: 0l1 7 1|1 1 4 6 210 2 5 8 8 9 312 6 9 414 6 8 510 0 What is the third quartile of the scores? O41 O 44 O 39.5 43.5 O 41.5

What percent of the data fall between the 1st and 2rd quartiles?   1. 0%   2. 25%   3. 50%   4. 75%   5. 100%

In a study to estimate the proportion of residents in a certain city and its suburbs who favor the construction of a nuclear power plant, it is found that 77 of 125 urban residents favor the construction while only 56 of 100 suburban residents are in favor. Is there a significant difference between the proportions of urban and suburban residents who favor construction of the nuclear plant? Make use of a P-value. Click here to view page 1 of the standard normal distribution table. Click here to view page 2 of the standard normal distribution table. Let urban residents correspond to population 1, let suburban residents correspond to population 2, and let a success be a resident who favors the construction of a nuclear power plant. Identify the null and alternative hypotheses. A. Ho: P₁ = P2 H₁: P₁ P2 D. Ho: P₁ #P2 H₁: P₁ = P2 Find the test statistic. ... Find the P-value. B. Ho: P₁ = P2 H₁: P₁ P2 E. Ho: P₁ = P2 H₁: P₁ P2 .85 (Round to two decimal places as needed.) (Round to three…
