Researchers surveyed samples of freshmen studentsand senior students about their spending habits. Amongseveral questions, they asked the students how much they spent on fast food during the past week. Here is a sum-mary of the responses:Which best describes the two variables in this study,money spent on fast food and high school class?A) Disjoint and independentB) Disjoint but not independentC) Independent but not disjointD) Neither independent nor disjointE) Independence cannot be determined because thesample sizes are unequal. *$10 $10–20 +$20 TotalFreshmen 23 12 8 43Seniors 25 19 28 72Totals 48 31 36 115

O.J. Juice Company sells bags of oranges and cartonsof orange juice. O.J. grades oranges on a scale of 1 (poor)to 10 (excellent). O.J. now has on hand 100,000 lb of grade9 oranges and 120,000 lb of grade 6 oranges. The averagequality of oranges sold in bags must be at least 7, and theaverage quality of the oranges used to produce orange juicemust be at least 8. Each pound of oranges that is used forjuice yields a revenue of $1.50 and incurs a variable cost(consisting of labor costs, variable overhead costs, inventorycosts, and so on) of $1.05. Each pound of oranges sold inbags yields a revenue of 50¢ and incurs a variable cost of20¢. Formulate an LP to help O.J. maximize profit.
Spam Spam filters try to sort your e-mails, deciding whichare real messages and which are unwanted. One methodused is a point system. The filter reads each incominge-mail and assigns points to the sender, the subject, keywords in the message, and so on. The higher the point total,the more likely it is that the message is unwanted. The filterhas a cutoff value for the point total; any message ratedlower than that cutoff passes through to your inbox, and therest, suspected to be spam, are diverted to the junk mailbox.We can think of the filter’s decision as a hypothesistest. The null hypothesis is that the e-mail is a real messageand should go to your inbox. A higher point total provides evidence that the message may be spam; when there’s suf-ficient evidence, the filter rejects the null, classifying the message as junk. This usually works pretty well, but, ofcourse, sometimes the filter makes a mistake.a) When the filter allows spam to slip through into yourinbox, which kind of error is…
An insurance agency services many customers who have purchased both a homeowner’s policy and a car policy from the agency. For each type of policy, a deductible amount must be specified. For a car policy, the choices are $0, $50, and $100, and 25%, 25%, and 50% of customers have these deductibles respectively. It means P(X=$0) = 0.25, etc. For a homeowner’s policy, the choices are 0, $200, and $500 and 30%, 30%, and 40% of customers have these deductibles respectively. It means P(Y=$0) = 0.3, etc. Suppose an individual with both types of policy is selected at random from the agency’s files. Let X = the deductible amount on the car policy and Y = the deductible amount on the homeowner’s policy. Assume X and Y are independent. a. Find the joint probability mass function of X and Y (write it as a table). b. Find median car insurance policy deductible. c. Find average homeowner’s policy deductible.

Consumer Preferences. In 2018, consumer goods giant Procter and Gamble (P&G) had more than 20 brands with more than $1 billion in annual sales (P&G website). How does a company like P&G create so many successful consumer products? P&G effectively invests in research and development to understand what consumers want. One method used to determine consumer preferences is called conjoint analysis. Conjoint analysis allows a company to ascertain the utility that a respondent in the conjoint study places on a design of a given product. The higher the utility, the more valuable a respondent finds the design. Suppose we have conducted a conjoint study and have the following estimated utilities (higher is preferred) for each of three different designs for a new whitening toothpaste. At the .05 level of significance, test for any significant differences.a. Use the Excel data analysis tool to perform the required test.b. What are the null and alternative hypothesis?c. What is the…
Group I nesting boxes were well separated from each other and well hidden by availablebrush. There were a total of 480 eggs in group I, of which a field count showed about275 hatched. Group II nesting boxes were placed in highly visible locations and groupedclosely together. There were a total of 874 eggs in group II boxes, of which a field countshowed about 272 hatched. Find a point estimate ˆp1 and ˆp2 for the proportion of eggsthat hatch in group I nest boxes and group II nest boxes. Let p1 and p2 be the populationproportion of hatched count in boxes I and II respectively.

Please do not give solution in image formate thanku. A school psychologist wants to determine if reprimanding in public (in front of the class) or private is more effective for curbing behavior. He randomly selects 12 students whose teachers reprimand in private and 12 students whose teachers reprimand in public. At the end of the year he determines the number of misbehaviors for each student. For the public condition and mean=7.7 and s=4.1 for the private condition mean=4.2 and s=3.5. Which method is more effective? What is the percentage of variance accounted for by the method of reprimand? What is the power of your test?
