- In order to conduct an experiment, 5 subjects are randomly selected from a group of 43 subjects. How many different groups of 5 subjects are possible.If a classroom of 32 students has 7 males (5 of who are single and 2 who are married) and 25 females (7 who are single and 18 who are married), what is the probability of selecting a single female randomly?You're a sociologist studying whether grocery prices are different in the inner cities than they are in the suburbs. To investigate this, you pick a random set of items (a basket of goods), and then send shoppers to buy these items at an inner city (IC) grocery, and also at a suburban (SU) grocery. You pick 27 different baskets of goods, so your secret shoppers buy 27 baskets, once at the inner city store, and once at a suburban store. The data is given in the dataset named "ICvSU_2799.xls", which you can find in data folder under Course Documents. Prices could be higher in the inner city because of discrimination, or they could be higher in the suburbs because of the greater disposable income. Use Excel to test the research hypothesis that inner city prices are different than the suburb's prices. The null hypothesis is that inner city prices are equal to suburban prices. You test at the alpha = 0.01 significance level. What do you conclude? Are prices the same? Who has higher…

The table below gives percentages of nonconforming cans, categorized by the type of nonconformity, for each of the three lines during a particular year. During this period, line 1 produced 500 nonconforming cans, line 2 produced 400 such cans, and line 3 was responsible for 600 nonconforming cans. Suppose that one of these 1500 cans was selected at random. Table attached in Image. a. What is the probability that the can was produced by line 1? b. What is the probability that the reason for nonconformance is a crack? c. If the selected can came from line 1, what is the probability that it had a blemish? d. Given that the selected can had a surface defect, what is the probability that it came from line 2?
- A restaurant buys avocados from three suppliers P, Q and R. Records show that 30% of the avocadoscome from P, 55% come from Q and the rest come from R. Further records show that 8% of avocadossupplied by P are substandard, 12% of avocados supplied by Q are substandard and 15% ofavocados supplied by R are substandard. A chef working at the restaurant randomly selects an avocado and finds it to be substandard. Calculate the probability that this avocado came from supplier Q. The manager of the restaurant notices that customers arrive at the restaurant at an average rate of 10customers per hour. Assume a Poisson distribution.2.1 Determine the probability that exactly 7 customers arrive in a given hour.A bowl contains 13 marbles of which 4 are red, 3 are white, and 6 is black. One marble is selected at random from the bowl and the color is observed. The possible outcomes are {red, white, black} Is each outcome equally likely? ? ◊ Which outcome is more likely? Select an answer P(White) = Give answer as a fraction.When planning a date night, you have a choice of 2 types of restaurants: pizza (P) or barbeque (B); a choice of 4 types of movies: romantic comedy (R), action/adventure (A), drama (D), or foreign film (F); and a choice of 2 types of post-movie activities: grabbing coffee (C) or getting ice cream (I). If you are choosing only one of each, list the sample space in regard to the dates (combinations of restaurants, movies, and post-movie activities) you could pick from.

Use Excel to test the research hypothesis that inner city prices are different than the suburb's prices. The null hypothesis is that inner city prices are equal to suburban prices.

Who has higher prices?…Management of a company that produces a medical device has carefully selected and screened 220 finished items (packaged, ready to ship). The team agrees that the sample contains 33 defective items, all for various visual defects on the package such as crooked labels, poor seal, errant marks on package, etc. The items are then given to an inspector for classification into “defective” and “non-defective” piles. The inspector ends up rejecting 9 non-defective items, and accepting 11 defective items. The inspector classifies the remaining items in the sample correctly. Find the following (answer as a probability, NOT a percentage. Use 3 decimal places. Notice that alpha = 9/187, Beta = 11/33, and p = 33/220. P(inspector accepts the item and its actually non-defective) =A warehouse employs 28 workers on first shift, 17 workers on second shift, and 11 workers on third shift. Eight workers are chosen at random to be interviewed about the work environment. Find the probability of choosing exactly five first-shift workers. The probability of choosing exactly five first-shift workers is (Round to three decimal places as needed.)
