**Educational Content: Statistical Analysis of Celebrity Net Worth****Data Overview**The following data represents the net worth (in millions of dollars) of the ten wealthiest celebrities in a country:- 249 million- 203 million- 175 million- 172 million- 164 million- 151 million- 146 million- 146 million- 141 million- 141 million**Objective**The task is to construct a 90% confidence interval for the population mean ($ \mu $) of the net worth of all celebrities based on this sample. Additionally, we are to determine if the data is from a normally distributed population as required for accurate interval estimation.**Graphical Explanation**The prompt does not include a graphical representation, but a horizontal line is shown, likely as a separator. There are empty fields for input below the line where the confidence interval is to be recorded.**Question**What is the confidence interval estimate of the population mean $ \mu $?Input Format:\[ \text{\$} \_\text{ million} < \mu < \_\text{ million} \](Round to one decimal place as needed.)

A study of seat belt users and nonusers yielded the randomly selected sample data summarized in the accompanying table. Use a 0.05 significance level to test the claim that the amount of smoking is independent of seat belt use. A plausible theory is that people who smoke are less concerned about their health and safety and are therefore less inclined to wear seat belts. Is this theory supported by the sample data? E Click the icon to view the data table. Determine the test statistic. *= (Round to three decimal places as needed.) Determine the P-value of the test statistic. P-Value (Round to three decimal places as needed.) Use a 0.05 significance level to test the claim that the amount of smoking is independent of seat belt use. A plausible theory is that people who smoke are less concerned about their health and safety and are therefore less inclined to wear seat belts. Is this theory supported by the sample data?

Heart rates are determined before and 30 minutes after a Kettleball workout. It can be assumed that heart rates (bpm) are normally distributed. Use the data provided below to test to determine if average heart rates prior to the workout are significantly lower than 30 minutes after a Kettleball workout at the 0.02 level of significance. Let 41 = mean before workout. before 70 68 69 74 72 67 61 after 73 69 76 76 72 71 63 Select the correct Hypotheses: Ho: Ha 12 Ho:1 = µ2 Ho:Hd = 0 Ho:µd >0 Ha:Ha > 0 Ha:H1 > H2 Ha:i < µ2 Ha:µ1 + µ2 Ha:Hd # 0 Ha:µd <0 Test Statistic = [three decimal accuracy] p-value = [three decimal accuracy] Conclusion: O Fail to Reject Ho O Reject Ho Interpret the conclusion in context: O There is not enough evidence to suggest the mean bpm before a Kettleball workout is lower than 30
ch.8 proportions question4 Assume that a sample is used to estimate a population proportion p. Find the 99% confidence interval for a sample of size 143 with 65% successes. Enter your answer as an open-interval (i.e., parentheses) using decimals (not percents) accurate to three decimal places.C.I. =
Ch. 6.1 CI We examine the effect of different inputs on determining the sample size needed to obtain a specific margin of error when finding a confidence interval for a proportion. Find the sample size needed to give, with 95% confidence, a margin of error with +/- 6% when estimating a proportion. Within +/- 4%. Within +/- 1%. (Assume no prior knowledge about the population proportion p). Comment on the relationship between the sample size and the desired margin of error.
Question3: It is known that the population wellbeing level follows a normal distribution. The wellbeing levels of 9 male is shown below. 2 | 247 3 | 34569 4 | 7 Use the sample data to calculate the 95% confidence interval Would we reject the hypothesis that the male has a statistically significant different wellbeing level from female at a 1% significance level? (hint: use the data above to conduct a statistic test, specify 4 steps)
I need help with a stat problem, section 7.2 and 7.3, thank you (please help with TI-84 commands) You receive a brochure from a large university. The brochure indicates that the mean class size for full-time faculty is fewer than 32 students. You want to test this claim. You randomly select 18 classes taught by full-time faculty and determine the class size of each. The results are shown in the table below. At α=0.10, can you support the university's claim? Complete parts (a) through (d) below. Assume the population is normally distributed. 38 29 29 31 30 41 25 23 30 27 31 33 36 31 29 32 27 23 (a) write the claim mathematically and identify Ho and Ha. (b) use technology to find the P-value. P= _____________(round to 3 decimal places) (c) decide whether to reject or fail to reject the null hypothesis. Which of the following is correct? A. reject Ho because the P value is less than the significance level. B. reject Ho because the P value is greater…
