The population is the whole set of data that are used for study and its unknown value of the population is parameter that explains the population behavior. Sample is the subset of the population that explains the characteristic of the population. The unknown value of the sample is statistic that explains the sample behavior. Some of the parameters are μ, σ etc., and some of the statistic are x¯, s etc., Given : The survey on American community survey polls household yearly as 3.5 million The observations given as, x¯ s n Male 55890 68767.88 470 Female 29240 32025.98 373 a) Parameter of interest : In the given experiment, the parameter of interest is average salary of household yearly and its point estimates are sample of average female salary and average male salary. Thus, from the given table values the point estimate of male is 55890 and female is 29240.b) Claim : The average salaries of male and females are different. Let the null and alternate hypothesis as, H0 : μ1=μ2H1 : μ1≠μ2 Level of significance is 0.10 Test statistic : z=x¯1-x¯2s12n1+s22n2=55890-2924068767.882470+32025.982373=7.45 Test statistic is 7.45 The z critical value at 0.10 is 1.645 Since the critical value is greater than critical value, the null hypothesis is rejected. Hence it is concluded that the average salaries of male and females are different.

A 2014 Pew Research Center Survey asked 2,002 adults about the intersection of politics and science. Of the survey participants, 1,281 responded "neither" when asked if they perceive scientists as politically liberal or conservative. What are the values of p′, "successes", or the estimated proportion of Americans who perceive scientists as neither politically liberal or conservative, and q′, the estimated proportion of Americans who perceive scientists as politically liberal or conservative?

3. Consumer Reports recently followed up with a survey to its readers asking about political preferences and primary choice of mobile device. There was a total of 11,214 Republican respondents. Of the 9,500 Democrats responding, 470 reported using a device not listed and 292 said they used a Windows phone. The total usage of Android devices recorded totaled 8,926; 3,921 of Android users were Republicans. Interestingly, there were an equal number of Apple and Android users reporting as Republicans. There were 4,528 Democrats using an Apple device. Only 2,672 of those surveyed reported as Independent, 51 said they used a Windows device and 428 said they used an Apple device.

In a study researching how donating to charity can affect a person's happiness, 96 participants were given $5 a day for one week. Each participant was randomly assigned to one of two groups. Those assigned to the first group were asked to spend the money on themselves, and those assigned to the second group were asked to donate the money to charity. At the end of the week, all of the participants were asked to rate their overall level of happiness on a scale from 0 to 100, with higher scores indicating greater levels of happiness. Which of the following are the appropriate null and alternative hypotheses to test whether the sample data provide convincing statistical evidence that donating to charity results in greater happiness than spending on oneself, on average? Ho self- "charity = 0 (A) Ha self charity >0 Ho self Mcharity=0 (B) Ha self charity 0 (E) Ha self = Mcharity <0
Use the following information to answer the question. Many couples believe that it is getting too expensive to host an "average" wedding in the United States. According to the website www.costofwedding.com,theaveragecostofaweddingintheU.S.in 2009 was $24,066. Recently, in a random sample of 40 weddings in the U.S. it was found that the average cost of a wedding was $23,224, with a standard deviation of $2,903. On the basis of this, a 9 5% confidence interval for the mean cost of weddings in the U.S. is $22,296 to $24,152. Does the confidence interval provide evidence that the mean cost of a wedding has decreased? Explain your reasoning.

The National Assessment of Educational Progress (NAEP) includes a mathematics test for eighth‑grade students. Scores on the test range from 00 to 500.500. Demonstrating the ability to use the mean to solve a problem is an example of the skills and knowledge associated with performance at the Basic level. An example of the knowledge and skills associated with the Proficient level is being able to read and interpret a stem‑and‑leaf plot. In 2019, 147,400147,400 eighth‑graders were in the NAEP sample for the mathematics test. The mean mathematics score was ?⎯⎯⎯=282.x¯=282.

Cris Turlock owns and manages a small business in San Francisco, California. The business provides breakfast and brunch food, via carts parked along sidewalks, to people in the business district of the city. Being an experienced businessperson, Cris provides incentives for the salespeople operating the food carts. This year, she plans to offer monetary bonuses to her salespeople based on their individual mean daily sales. Her first task is to see if there is a significant difference in the mean daily sales among the different salespeople. She chooses a "sample" of days for each salesperson and records the sales for each day. She then runs a one-way, independent-samples ANOVA test to determine whether or not she can conclude that at least one salesperson's performances is significantly different from the others. (Otherwise, she'll split the bonuses evenly among all the salespeople.) In her ANOVA, the "groups" are the different salespeople, and the variable of interest is the daily sales…
