Give a solution based on the example. You do not need to solve them just note which test to use from the ones stated in the "Part 1" directions.

Name: . Blaine Nowak Date: 11/9/ 22 PSYC 3402 Take-home Exam 3 Part I: Determine the best hypothesis test to recommend for each scenario presented below. Use the following tests as recommendations: One sample z test, One sample / test, Independent samples t test, Dependent samples t test. (1 point each): 1) A study was performed to test whether cars get better mileage on premium gas than on regular gas. Each of 10 cars was first filled with either regular or premium gas, decided by a coin toss, and the mileage for that tank was recorded. The mileage was recorded again for the same cars using the other kind of gasoline. Dependent Samples t test 2) A researcher predicted that the Dunder Mifflin Paper Company makes more sales than the average paper company in the United States. To test this, the researcher collects the sales data from a small sample of 6 Dunder Mifflin employees and compares this to the national average of sales from similar paper companies. One Sample I test 3) The campus board wants to observe two groups of students who are going to be registering for classes to see if there's a difference in time efficiency between those who use an advisor before registering and those who don't. The first group of 10 students meets with an advisor before their registration. The second group of 10 students doesn't meet with an advisor before their registration. Did the students who met with an advisor before registering experience shorter registration times? Dependent Samples t-test 4) A study was performed to test eyewitness accuracy. Pairs of participants entered a room believing they would be participating in a gambling experiment. Each participant was given $10 in coins to play poker with. The participants were randomly seated near the door or away from the door. After 15 minutes, an actor dressed in street clothes burst into the room, and stole the money from the participant near the door. The "thief" was later caught, and both participants were asked to identify him in a line-up. Eyewitness accuracies from the participants were then compared. independent samples t- test 5) To test the effects of cartoons on cognitive functioning, a researcher assigns 15 children to watch 30 minutes of Spongebob Squarepants, and 15 more children to color for 30 minutes. The research then tests all children on the same cognitive functioning task. independent sampost test 6) A researcher who studies the amount of hours that students get a day wanted to know if college students who had an assignment due would sleep less than if they did not have any assignments due. The researcher picked 7 random students from the PSYC 3402 class and had them write down the amount of sleep they got (in hours) when they did not have an assignment due, and then the amount of sleep they got (in hours) when they were given an assignment, which had to be completed the same day it was given out. Dependent: Samples t test 7) A statistics student is curious about what kind of dessert to make for a family get-together, but can't decide between making a traditional dessert or a Greek dessert. She believes the traditional dessert will be liked better, but decides to use her newfound knowledge to determine if this is truly the case. She collects a group 23 of friends and neighbors to try the two desserts and determine which one is more preferred. First, the sample a chocolate cheesecake and then baklava. After trying each desert the friends and neighbors rate the dessert on a preference scale. t test 8) The average price for turnips in Animal Crossing: New Horizons is 95 bells (this distribution is not normal). Samantha believes that selling on Tuesday mornings will sell for more than average. To test this, she sells her turnips on Tuesday mornings for 20 weeks, noting the average price during this time. one sample 2 test 9) A dog breeding enthusiast argues that Chiweenie (Chihuahua dachshund hybrid) are the most adorable dogs. Her colleague claims that Pomsky (Pomeranian husky hybrids) are the cutest. To test this, they collect one sample to rate both dog breeds by cuteness. t test 10) A parakeet breeder believes that she raises healthier and longer-lived parakeets than those bought from pet stores. After contacting the pet stores to determine the average lifespan of store bought parakeets, she then determines the average lifespan of a sample of 18 of her own birds. test
