Lilo wants to know if equal proportions of students in her class know how to surf well, know how to surf a little or do not know how to surf. She randomly samples 60 students in her class and asks them if they know how to surf. Twenty students indicate that they do not know how to surf 'don't know', while 30 students indicate they know how to surf well 'know well,' and 10 students indicate they know how to surf ‘a little’. State the hypothesis being tested by Lilo (H0 and HA)? Test Lilo's hypothesis at α of .05. Enter the test statistic, critical value, and decision as part of your answer. Test statistic = Critical value = Do you reject or retain the null hypothesis that the slope is not different from zero? (Enter "Reject" or "Retain"):
240 students responded to the imaginary student canteen survey. The survey asked whether the student chose a meat or vegetable dish for lunch. In addition, we asked for an opinion on the quality of the food on a scale of 1-5, where 1 means the worst and 5 the best. 131 of the students chose vegetarian food and 109 meat food. Of those who chose vegetarian food, 17 students gave a grade 1, 25 students gave a grade 2, 38 students gave a grade 3, 35 students gave a grade 4, and 16 students gave a grade 5. Of those who chose the meat dish, 14 students gave a grade 1, 29 students gave a grade 2, 42 students gave a grade 3, 20 students gave a grade 4, and 4 students gave a grade 5. Use the function chisq.test() to test the null hypothesis that the choice of lunch is not connected to the opinion about the quality of the food. What is the p-value? Give the answer to three decimal places. Remember the correct decimal separator.
A consumer agency wants to determine which of two laundry detergents, A or B, cleans clothes better. Fifty pieces of fabric are subjected to the same kinds of stains (grass, mud, coffee). Then 25 pieces are randomly assigned to be cleaned with detergent A and the remaining 25 pieces are cleaned with detergent B. After being laundered, the pieces of fabric are rated on a scale from 1–10, with 1 being the least clean to 10 being the most clean. The difference in mean ratings (A – B) was determined to be 1.5. Assuming there is no difference in the two detergents, 200 simulated differences in sample mean ratings are displayed in the dotplot. Using the dotplot and the difference in mean ratings from the samples, is there convincing evidence that the one detergent is better than the other? Yes, because a difference in mean rating of 1.5 or more occurred only 23 out of 200 times, meaning the difference is statistically significant and there is convincing evidence that A is more effective…

Three-circle, red-on-white is one distinctive pattern painted on ceramic vessels of the Anasazi period found at the Wind Mountain archaeological site. At one excavation, a sample of 166 potsherds indicated that 80 were of the three-circle, red-on-white pattern. How many ceramic potsherds must be found and identified if we are to be 95% confident that the sample proportion p̂ of such potsherds is within 6.5% of the population proportion of three-circle, red-on-white patterns found at this excavation site?
