Answer for question D)
We are interested in looking at the effect of a baseball player’s free agent status on their salary. We look at 337 baseball players and categorize them as either having a high salary (above 2 million) or not, and as either being free agents or not. ------------------------------------- You also wonder if having a high batting average affects the salary of baseball players. You classify all 370 baseball players as having a high batting average if it is over .300. 1. What are the variables you are looking at? What are the possible categories within each variable? Which is the explanatory, and which is the response? 2. If we want to perform a χ2 test to see if there is a relationship between the two variables, what is our null and alternative hypothesis?
A market investigator returns the following data of 10000 people consulted : 8110 liked chocolates, 7520 liked toffee, 4180 liked boiled sweets, 5700 liked chocolates and toffee, 3300 liked chocolates and boiled sweets, 3480 liked toflee and boiled sweets, and 2970 liked all the three. Show that this information as it stands must be incorrect.
A study was conducted to determine whether big-city and small-town dwellers differed in their helpfulness to strangers. In this study, the investigators rang the doorbells of strangers living in a large City or small towns in the vicinity. They explained they had misplaced the address of a friend living in the neighbourhood and asked to use the phone. The following data show the number of individuals who admitted or did not admit the strangers (the investigators) into their homes: Helpfulness to strangers Admitted strangers into their home Didnot admit strangers into their home Big city dwellers 60 90 Small town dwellers 70 30 State the dependent and independent variable Is this a directional or non directional

A contestant pays $0.55 to randomly catch one fish and receives $0.35 if the fish is orange, $1.15 if the fish is silver, and $15.00 if the fish is red. How much (on average) does the carnival gain on each play? (If the carnival looses money, enter a negative dollar amount)
You may need to use the appropriate appendix table or technology to answer this question. In a recent poll six hundred adults were asked a series of questions about the state of the economy and their children's future. One question was, "do you expect your children to have a better life than you have had, a worse life, or a life about the same as yours?" Suppose the responses showed 251 better, 303 worse, and 46 about the same. Use the sign test and a = 0.05 to determine whether there is a difference between the number of adults who feel their children will have a better life compared to a worse life. State the null and alternative hypotheses. (Let p = the proportion of adults who feel their children will have a better life.) OH: P≥ 0.50 H₂: P 0.50 O H₂: P = 0.50 H₂: P = 0.50 O Ho: P < 0.50 H₂: P = 0.50 Find the value of the test statistic. (Round your answer to two decimal places.) z = -2.21 x Find the p-value.

Suppose a researcher is interested in examining the relationship between a person's gender and whether he or she likes the taste of Vegemite (a dark- brown food paste, made from yeast, that is popular in Australia). She collects a sample of n = 10 people and asks them whether they like the taste of Vegemite. The following table summarizes the results. Male Female Does Not Like the Taste of Vegemite 4 1 Likes the Taste of Vegemite 2 3 The researcher wants to calculate the correlation between a person's gender and whether he or she likes the taste of Vegemite. To do so, the researcher first creates a table of the data by converting each variable to a numerical value. She assigns 0 to "male" and 1 to "female." She then assigns 0 to "does not like the taste of Vegemite" and 1 to "likes the taste of Vegemite."

A psychologist investigating treatments for headaches believes that training in relaxation will reduce the number of reported headaches. A group of nine subjects are taught to induce the relaxation response as a method of managing their headaches. The number of headaches for a 1- week period before treatment is recorded as a baseline. After training the number of headaches for another 1-week period is recorded by these same subjects. Baseline After Training 17 3 13 7 6 2 5 3 5 6 10 2 8 1 6 0 7 2 Analyze this data.
