Help me solve questions 15-17 using the following data ### Chi-Square Test for Independence of US Senators' Party Affiliation and Spending#### Problems 12-17The table below presents data on the number of US Senators from each political party based on their federal spending in three spending categories. The table is intended to aid in the calculation of the Chi-square test for independence, specifically at the 0.05 significance level. The table includes blanks that need to be filled to arrive at both row and column totals. You need to:1. Record the total number of data points for each spending category and political party.2. Perform a Chi-square test to determine whether there is a significant relationship between party affiliation and spending.#### Table: Number of US Senators by Party and Spending Category| | Less than 4 Billion | 4 to 7 Billion | More than 7 Billion | Totals ||------------------|---------------------|----------------|----------------------|--------|| **Democrat** | 12 | 19 | 16 | 47 || **Republican** | 8 | 15 | 22 | 45 || **Totals** | 20 | 34 | 38 | 92 |#### Explanation of the Table:- The rows represent the party affiliation of the Senators (Democrat or Republican).- The columns represent different categories of federal spending: Less than 4 Billion, 4 to 7 Billion, and More than 7 Billion.- The last column provides the total number of Senators for each party.- The last row provides the total number of Senators in each spending category.- The bottom-right cell provides the overall total number of Senators included in the table (92).This setup is integral for computing the expected frequencies and conducting the Chi-square test for the independence of party affiliation and federal spending habits. You will fill in any missing data points and compute the necessary statistical measures to draw a conclusion about the relationship between the variables. ### Statistical Analysis Exercises---#### Problems 18-22**15. Calculate $\chi^2$ for this sample data.**- a. 1.75- b. 2.17- c. 3.02- d. 4.76**Ans.** _______---**16. Instead of using your $\chi^2$ for number 14, let's say $\chi^2$ = 6.0. If the degrees of freedom is 2, what is the p-value for this problem? (If you use the table in the book, choose the value below that fits in the range you find.)**- a. 0.050- b. 0.010- c. 0.928- d. 0.298**Ans.** _______---**17. Let's say you fail to reject the Null hypothesis for this problem. Choose the best conclusion.**- a. At $\alpha$ = 0.05, the data indicate that property and spending are independent.- b. At $\alpha$ = 0.01, the data indicate that property and spending are independent.- c. At $\alpha$ = 0.01, the data indicate that property and spending are not independent.- d. At $\alpha$ = 0.05, the data indicate that property and spending are not independent.**Ans.** _______---These exercises involve the application and interpretation of the Chi-square ($\chi^2$) statistic, p-values, and hypothesis testing. Review the relevant statistical concepts and techniques as needed to solve these problems.*Note: There are no graphs or diagrams in the provided text.*

(For Questions 25 -27). A consumer group wanted to determine if there was a difference in customer perceptions about prices for a specific type of toy depending on where the toy was purchased. In the local area there are three main retailers: W-Mart, Tag, and URToy. For each retailer, the consumer group randomly selected 5 customers, and asked them to rate how expensive they thought the toy was on a 1-to-10 scale (1= not expensive, to 10 = very expensive). The toy was priced the same at all retail stores. The data collected is reported in the table below. W-Mart Tag URToy 8 5 4 9 4 2 10 6 1 9 3 5 9 5 4 MW = 9 MT = 4.6 MU = 3.2 SSW = 2 SST = 5.2 SSU = 10.8 25. What kind of statistical test should be used to test the consumer group's research goal, assuming that the researcher wanted to use the 1-to-10 scale as a numerical interval measure?

Baldur is very interested in statistics and spinning and he decided to combine these two interests and carry out the following research. He randomly selected 100 Reykjavik residents and asked them two questions. On the one hand whether they want chocolate, ice cream or caramel on their pacifier and on the other hand what gender they are. Questions 4-6 deal with Baldur's survey. Baldur's question: "What do you want most on your spinner?" Has three possible answers:1) chocolate, 2) ice cream, 3) caramel, What type is the variable that Baldur records? 1. Continuous category variables. 2. Continuous number variables. 3. Unordered category variables. 4. Sorted category variables. Baldur is interested in investigating whether there is a connection between the two variables, gender and what people want on their spinner. What kind of hypothesis test should Baldur use? 1. Ki-square test. 2. Hypothesis test for two averages. 3. Variance analysis. 4. Simple linear regression. Assume that the…

(For Questions 17-19 and 20-24). The following data was collected from a clinical trial testing a new drug aimed to lower blood pressure for individuals older than age 45. Half of the 20 participants received the new drug (Treatment = Yes) and the other half of the participants received a placebo pill (Treatment = No). Their age and gender was also recorded. Please use this data for Questions 17-19 and 20-24 and note, not all the information in the table will be used for either problem, you must decide what is relevant based on what the problem is asking.

USE THE INFORMATION BELOW TO ANSWER QUESTIONS 34 THRU 37 The infant mortality rate is expressed as the number of infant deaths per 1000 live births. According to the US Central Intelligence Agency (CIA), which keeps accurate, up-to-date infant mortality statistics throughout the world, in 2019 there were 33 nations with better infant mortality rates than the United States. The US infant mortality rate of 6.22 infant deaths per 1000 live births ranked 34th. It appears that at a certain stage in nations' movement up the socioeconomic scale-after the basic necessities for infant survival (proper nutrition, sanitation, clean water, and access to health care) have been met-a counter-intuitive relationship occurs between best fit line and the number of vaccines given to infants and infant mortality rates: nations with higher (worse) infant mortality rates give their infants, on average, more vaccine doses. This positive correlation, derived from the data elicits an important inquiry: are…
