PLS ANSWER QUESTIONS 13, 15, and 16 ..The house brand premium chocolate chip cookie for Sale Mart Supermarket is called Choco-Champs. The company sells them only in a small pack, claiming in advertisements that this sized package of cookies is figuratively bursting with about 250 real chocolate chips contained within the cookies. A consumer testing lab tech is double checking this claim, and has collected a random sample of 9 packs of Choco-Champs from as many randomly selected store locations. A technician appropriately cold washes the cookies and counts the chips in each package. The results of these cold washes were recorded as follows: 246 247 241 245 249 247 243 245 251 13. What is the chance of a Type I error in this context? Express this answer in whole percentage with percent symbol? 15. What is the p-value that corresponds with the test statistic value, expressed as a decimal rounded to the nearest thousandth? 16. Compute the lower and…
A flight attendant selects a random sample of 201 travelers. For each, he records the class in which the person travels and whether they have carry-on luggage. He would like to know if there is convincing evidence that the class in which a person travels is associated with having carry-on luggage. Let a = 0.05. What are the hypotheses for this test? O Ho: Class is not independent of carry-on luggage. Hg: Class is independent of carry-on luggage. O Họ: Class is independent of carry-on luggage. Hg: Class is not independent of carry-on luggage. O Họ: There is an association between class and carry-on luggage. Hạ: There is no association between class and carry-on luggage. O Ho: The proportion of travelers who have carry-on luggage is not the same in the types of class. Hg: The proportion of travelers who have carry-on luggage is the same in the types of class.
Refer to the following scenario. A government official is in charge of allocating social programs throughout the city of Vancouver. He will decide where these social outreach programs should be located based on the percentage of residents living below the poverty line in each region of the city. He takes a simple random sample of 122 people living in Gastown and finds that 24 have an annual income that is below the poverty line. For each of the following statements, specify whether the statement is a correct interpretation of the 95% confidence interval for the true proportion of Gastown residents living below the poverty line.

Research results indicate that physically attractive people are also perceived as being more intelligent (Eagly, Ashmore, Makhijani, & Longo, 1991). Asa demonstration of this phenomenon, a researcher obtained a set of 10 photographs, 5 showing men who were judged to be attractive and 5 showing men who were judged to be unattractive. The photographs were shown to a sample of n 5 25 college students and the students were asked to rate the intelligence of the person in the photo on a scale from 1 to 10. For each student, the researcher determined the average rating for the 5 attractive photos and the average for the 5 unattractive photos, and then computed the difference between the two scores. For the entire sample, the average difference was MD 5 2.7 (attractive photos rated higher) with s 5 2.00. Are the data sufficient to conclude that there was a significant difference in perceived intelligence for the two sets of photos? Use a two-tailed test with a 5 .05.

A store owner wanted to determine if more than 5% of customers made a purchase after he sent out a text. He sent out 300 texts to 300 randomly selected customers. Out of those 300, 17 made purchases. Is this evidence that if he sent out texts to all of his customers more than 5% would make purchases? What is the appropriate null and alternative hypothesis? Ho: p= 0.05 Ha: p> 0.05 O Ho: phat = 0.05 Ha: phat > 0.05 O Ho: p= 0.056 Ha: p > 0.056 O Ho: mu = 0.05 Hla: mu > 0.05
