You want to test the best way to maximize the fuel efficiency of Mercedes 30OD cars. You tinker with 40cars. Half of them are 1987, and half are 1985.Within each year of car, you randomly divide the 20 cars into four groups of 5 cars. For each group youapply a different modification, and you measure the fuel efficiency of each car once.Your research design looks something like this:Car Year Modification Efficiency1985 A1.X1......51985 A1985 BX6101985 BX1011 1985 CX11...151985 CX15161985 DX16.....201985 DX201987 AX21......251987 AX25261987 BX26L.........301987 BX30311987 CX31L....351987 CX35361987 DX36......401987 D40216. You want to know which modification works best, and if the modifications work differently for the differentyears.What type of test should you use?O CorrelationOt-test for two dependent groupsO Multiple RegressionO Repeated Measures ANOVAO tatistical Process ControlO Simple Linear RegressionO Multi-Way ANOVAO One-Way ANOVAOztestOt test for two independent groupsO chi-square test

In the given case we have a sample of a total of 40 cars, 20 are the 1987 model and 20 are the 1985…

Emily is trying to check if the nutritional content of different formulas have different effects on mice. She uses five mice to test each type of formulas (A, B, and C) and Formula A is simply a placebo. Each mouse's weight is recorded in grams. At the end of a specified time period, each mouse is weighed again and the net gain in grams is recorded as shown in Table 1 below.

Your Turn: The Gas Guzzler Tax is imposed on manufacturers on the sale of new-model cars (not minivans, sport utility vehicles, or pickup trucks) whose fuel economy fails to meet certain statutory regulations, to discourage the production of fuel-inefficient vehicles. The tax is collected by the IRS and paid by the manufacturer. The table (top right) shows the amount of tax that the manufacturer must pay for a vehicle's miles per gallon fuel efficiency. 12.5 13.5 MPG (M) 14.5 15.5 16.5 17.5 18.5 19.5 20.5 21.5 22.5 Tax per Car (T) $6400 $5400 $4500 $3700 $3300 $2600 $2100 $1700 $1300 $1000 $0 1.

Example 3: Alexis has a lengthy commute to work each day. There are two main routes that she takes on her way to work and they both average 40 minutes. Alexis likes to be able to predict how long before work she needs to leave in order to make it on time, and since both routes take the same average amount of time, she was interested in determining whether or not one route was more consistent with its timing. So she recorded how long it took her to drive to work 20 times total (Data shown below). Carry out an appropriate hypothesis test at the a = to determine if one route yields more consistent times than the other. 0.05 level %3D Route 1 41 42 41.5 40.5 41 40.5 40 39 40 42 Route 2 37 36 39 38 37 40 44 41 43 38 Standard Deviation Sample Size Route 1 0.950 10 Route 2 2.669 10

Frogs have been breeding like flies at the Enormous State University (ESU) campus! Each year, the pledge class of the Epsilon Delta fraternity is instructed to tag all the frogs residing on the ESU campus. Two years ago (t = 0) they managed to tag all 42,000 of them (with little Epsilon Delta Fraternity tags). This year's pledge class discovered that all the tags had fallen off, and they wound up tagging a total of 63,000 frogs. (a) Find an exponential model for the frog population. f(t) = (b) Assuming exponential population growth, and that all this year's tags have fallen off, how many tags should Epsilon Delta order for next year's pledge class? (Round your answer to the nearest integer.) tags
A researcher takes a sample of 40 introverts and 40 extroverts and asks them to solve problems in either a crowded room or an uncrowded room. The researcher measures the number of problems solved (numbers can range from 0 problems solved to 25 problems solved). Here are the results Crowded Room Uncrowded Room Introverts M = 12 M = 18 Extroverts M = 18 M = 12 Does there appear to be a main effect of room? Does there appear to be a main effect of personality (introversion/extraversion)? Does there appear to be an interaction between room and personality?
