Sample # 1 and has been provided in the second screenshot (hand written) **Proportion of Adult Females in the United States Registered to Vote**- **Sample Proportion (p̂):** - \( p̂ = 69\% = \frac{69}{100} = 0.69 \)- **Margin of Error (E):** - \( \text{Margin of Error} [E] = \pm 3\% \) - \( E = \pm \frac{3}{100} = \pm 0.03 \)- **95% Confidence Interval (CI):** - \( CI = p̂ \pm E \) - \( CI = 0.69 \pm 0.03 \) - \( CI = (0.69 - 0.03, 0.69 + 0.03) \) - \( CI = (0.66, 0.72) \)Interpretation:The confidence interval indicates that the proportion of adult females in the United States registered to vote lies between 0.66 and 0.72, which translates to 66% to 72%. **Question 2**: Based upon the results of the sample in #1, can you say with 95% confidence that your confidence interval contains the true percentage of all adult females registered to vote? Explain your answer.*Explanation*: The question asks about the confidence level of a statistical sample. A 95% confidence level implies that if the same population is sampled multiple times, approximately 95% of the confidence intervals calculated from those samples will contain the true population parameter. The explanation should include an interpretation of the specific results from the sample referred to in #1 and how it relates to this statistical concept.

Here we interpret the result given handwritten solution.

Basketball players can take shots worth 3 points, 2 points, or 1 point. A scout is assessing two players- Tabitha and Lauren-who play for different teams in different leagues. The scout wonders if they have similar or different shot selections. They take a random sample of Tabitha's games and a separate random sample of Lauren's games. They tally how many of each type of shot the players attempted in those games. Here is a summary and the results of a chi-square test: Chi-square test: Shot vs. player Tabitha Lauren 3-point 8 12 Expected 10.34 9.66 2-point 40 37 Expected 39.83 37.17 1-point 12 Expected 9.83 9.17 x² = 2.097, DF = 2, P-value = 0.350 %3D Assume that all conditions for inference were met. At the a = 0.05 significance level, what is the most appropriate conclusion to draw from this test? Choose 1 answer: This is convincing evidence that the distribution of shot type differs between Tabitha and Lauren.

A statistics teacher asked two different students, Lexie and Jennifer, to go to Wegmans and sample 30 shoppers each. The population of interest for both people can be defined as, “People who shop at the Johnson City, NY Wegmans store”. Here is what each person did to collect their sample: Lexie: She stood outside at the entrance to the store on 3 different days and times and surveyed every 15th person to walk by her. She surveyed 10 people each time to get her 30. Jennifer: She went to Wegmans after her nursing shift first thing Wednesday morning to buy deodorant since she ran out. When she was in the pharmacy area she surveyed all the people around her and then, to get up to 30 surveys, she went to the health food section and surveyed everyone she was there. Identify at least 2 specific reasons why Lexie’s approach is more likely to give a representative sample. Consider sources of bias, or types of shoppers who might be excluded by Jennifer’s approach.…
At a football game, 40 fans were randomly surveyed. Of the sampled fans, 6 named Daren as the best player.

The accompanying table shows the result of a national election along with the vote predicted by several organizations in the days before the election. The sample sizes were typically a bit above 1,000 people, and the reported margin of error was around plus or minus 4 percentage points.

As part of a statistics project, a teacher brings a bag of marbles containing 800 white marbles and 300 red marbles. She tells the students the bag contains 1100 total marbles, and asks her students to determine how many red marbles are in the bag without counting them. A student randomly draws 100 marbles from the bag. Of the 100 marbles, 32 are red. The data collection method can best be described as Survey Census Controlled study Clinical study The target population consists of The 1100 marbles in the bag The 300 red marbles in the bag The 32 red marbles drawn by the student The 100 marbles drawn by the student None of the above The sample consists of The 300 red marbles in the bag The 32 red marbles drawn by the student The 100 marbles drawn by the student The 1100 marbles in the bag None of the above Based on the sample, the student would estimate that marbles in the bag were red.
