Purchase of Generic Products A survey carried out for a supermarket classified customers according to whether their visits to the store are frequent or infrequent and whether they often, sometimes, or never purchase generic products. The accompanying table gives the proportions of people surveyed in each of the six joint classifications. Complete parts (a) through (h). Frequency of Visit Often Sometimes Never Frequent Infrequent 0.21 0.36 0.15 0.09 0.11 0.08 a. What is the probability that a customer is both an infrequent shopper and often purchases generic products? 0.09 (Do not round.) b. What is the probability that a customer who never buys generic products visits the store infrequently? 0.3478 (Round to four decimal places as needed.) c. Are the events "Never buys generic products" and "Visits the store infrequently" independent? V No O Yes d. What is the probability that a customer who frequently visits the store often buys generic products? 0.2917 (Round to four decimal places as needed.) e. Are the events "Often buys generic products" and "Visits the store frequently" independent? O No

Can someone please help me with part c on question 1?
A special education teacher did research on whether or not there is a relationship between the number of students in his class and the number incidents of “acting out” behaviors exhibited by the autistic students in the classroom. He collects data for a year and aggregates them by month. He obtained the statistics below, r= -.863 R2=.74 b= -1.212294 a= 131.176598 10.) How does the presence of more students affect the incidents in the class? a) as students are added the incidences increase b) as students are added the incidences decrease c) the number of students does not affect acting out d) the number of students caused more incidents How much of the variability of acting out is explained by the number of students in the class?___________

You Got Gas have developed a new type of fuel additive that supposedly increases car speed. Before they put it out on the market, however, they need to test if it really is a difference compared to standard fuel. So, they took 6 vehicles and calculated the time it takes to for them to drive 1 mile going as fast as they can. They received the following data: Car ID# Course time (standard fuel in minutes) Course time (w/ additive in minutes) 1 35 27 2 40 35 3 25 27 4 40 39 5 95 94 6 32 18 6. What is the null and research hypothesis for this study? 7. What type of statistical test should we use to compare means (z-test, independent t-test, dependent t-test, or ANOVA)? Why? 8. What are the degrees of freedom? What are the critical values for that statistical test with this data at α = 0.05? α = 0.01? 9. Comparing the groups, is there a significant difference at α = 0.05 in lap time between eating the name bran and when they ate Dog Go? 10. How would the researcher…
