Use the following information to answer the next 16 exercises. The Ice Chalet offers dozens of different beginning ice- skating classes. All of the class names are put Into a bucket. The 5 P.M., Monday night, ages 8 to 12, beginning ice-skating class was picked. In the class were 6.1 girls and 16 boys. Suppose that we are Interested in the true proportion of gixls, ages 8 to 12. In all beginning ice-skating classes at the Ice Chalet. Assume that the children in the selected class are a random sample of the population.
Using the same p and level of confidence. suppose that n were increased to 100. Would the error bound become larger or smaller? How do you know?

- BUSINESS DISCUSSarrow_forwardA researcher wishes to estimate, with 90% confidence, the population proportion of adults who support labeling legislation for genetically modified organisms (GMOs). Her estimate must be accurate within 4% of the true proportion. (a) No preliminary estimate is available. Find the minimum sample size needed. (b) Find the minimum sample size needed, using a prior study that found that 65% of the respondents said they support labeling legislation for GMOs. (c) Compare the results from parts (a) and (b). ... (a) What is the minimum sample size needed assuming that no prior information is available? n = (Round up to the nearest whole number as needed.)arrow_forwardThe table available below shows the costs per mile (in cents) for a sample of automobiles. At a = 0.05, can you conclude that at least one mean cost per mile is different from the others? Click on the icon to view the data table. Let Hss, HMS, HLS, Hsuv and Hмy represent the mean costs per mile for small sedans, medium sedans, large sedans, SUV 4WDs, and minivans respectively. What are the hypotheses for this test? OA.
