The table lists wholesale prices of fish in dollars from two companies—one on the East Coast and one on the West Coast—for various fish types. The task is to find a 90% confidence interval for the mean difference in wholesale prices between these suppliers. You should round answers to three decimal places and use four decimal places for any interim calculations.### Wholesale Prices of Fish in Dollars| Fish | East Coast | West Coast ||----------------|------------|------------|| Cod | 18.49 | 19.49 || Tilapia | 6.00 | 6.00 || Farmed Salmon | 18.99 | 23.99 || Organic Salmon | 24.45 | 31.45 || Grouper Fillet | 30.49 | 28.49 || Tuna | 29.15 | 36.15 || Swordfish | 21.55 | 22.55 || Sea Bass | 29.50 | 36.50 || Striped Bass | 30.49 | 33.49 |With a 90% confidence level, the task is to determine the true mean difference in wholesale prices between East Coast and West Coast suppliers, which lies between a specific dollar range.### Explanation- **Cod**: East Coast: $18.49, West Coast: $19.49- **Tilapia**: East Coast: $6.00, West Coast: $6.00- **Farmed Salmon**: East Coast: $18.99, West Coast: $23.99- **Organic Salmon**: East Coast: $24.45, West Coast: $31.45- **Grouper Fillet**: East Coast: $30.49, West Coast: $28.49- **Tuna**: East Coast: $29.15, West Coast: $36.15- **Swordfish**: East Coast: $21.55, West Coast: $22.55- **Sea Bass**: East Coast: $29.50, West Coast: $36.50- **Striped Bass**: East Coast: $30.49, West Coast: $33.49The blank spaces indicate where students would calculate the confidence interval values

The data shows the wholesale price of the east coast and west coast suppliers.

Several years ago, the state of California launched an aggressively advertisement campaign against smoking. We've interviewed students from 16 college campuses in California and recorded for each campus the percentage of students who claimed that they had encountered assay least one anti smoking advertisement on campus in the past month. Here are those percentages. 53 39 30 49 48 42 41 38 26 36 40 42 52 51 45 50 Construct a box and whisker plot for the data.
Mr. Palmer, has been teaching beginners how to fix their stroke for the last 10 years. The mean golfing score for all past students who learned with Mr. Palmer is 79. This golfing cycle, he tried a new teaching method using simulations instead of real-world golf. He then had 15 of his students that used his new method take a golfing test. Enter the data into SPSS. Use this dataset to answer this question: did Mr. Palmer’s students perform better on the golfing test using the new method as compared to the traditional teaching technique? 1. From the output, report the test statistic and the probability (obtained p-value, called “sig” in the output). Remember to include degrees of freedom when you report t-values. 2. Will you reject or fail to reject the null based on the SPSS output (Remember to use numbers from the output only to make your statistical conclusion. If you use a critical t, you will get no points.).

(a) TV stations use ratings to decide which shows to keep or cancel. Therefore, the A. C. Nielsen Company collects data on the TV viewing habits of Americans and publishes the information in Nielsen Report on Television. Suppose that you want to use a paired sample to decide whether the mean viewing times of married men and married women differ: 1. Identify the variable. 2. Identify the two populations. 3. Identify the pairs. 4. Identify the paired-difference variable.

Here is an example from John and Jenn. When we return exams in our classes, we find it beneficial to share with students information on the distribution of scores. We provide this information so that students will have an idea of how they scored on the exam in comparison to their peers. However, deciding which descriptive information to provide to the class is not always an easy decision. These are modified grades from one of Jenn’s statistics classes. For this data set, the mean is 77, the mode is 92, and the median is 86. If you were the professor of the class, do you think sharing the mean scores on the exam with the class is a representative score of the data set? Why or why not? 9 or 11. The researchers predicted that the more a mother weighed during pregnancy, the higher the fat mass would be in the child. Such findings would support the developmental over nutrition hypothesis, which states that overeating during key developmental times has an influence on the offspring. The…
The study sorted PIR data into three categories: Use the graphs to estimate the following information from the study. You may wish to record your responses for use in later questions. Part A: The total number of obese men is about million. Part B: The total number of obese women is about million. Part C: The number of obese men with PIR<130% is about million. Part D: The number of obese women with PIR<130% is about million.

what would happen to the mean, median, and mode values that you calculated ,if you added one player to the team whose points per game for the season was 25. just tell me if the mean, median, and mode would go up, down, or stay the same. Give an example of variable for which the mean would not be appropriate to describe the data (that is, tell me a circumstance in which you would not want to use the mean to describe a dataset)
On average, a sample of n = 36 scores will provide a better estimate of the population mean than a sample of n = 49 scores from the same population.
