An article reported that, in a study of a particular wafer inspection process, 356 dies were examined by an inspection probe and 216 f these passed the probe. Assuming a stable process, calculate a 95% (two-sided) confidence interval for the proportion of all dies that pass the probe. (Round your answers to three decimal places.)1x)You may need to use the appropriate table in the Appendix of Tables to answer this question.

It is given that Sample size n = 356 Number of dies pass the probe, X = 216 Confidence level = 95%…

Question 18 A smart phone manufacturer is interested in constructing a 95% confidence interval for the proportion of smart phones that break before the warranty expires. 87 of the 1503 randomly selected smart phones broke before the warranty expired. Round answers to 4 decimal places where possible. a. With 95% confidence the proportion of all smart phones that break before the warranty expires is between and b. If many groups of 1503 randomly selected smart phones are selected, then a different confidence interval would be produced for each group. About percent of these confidence intervals will contain the true population proportion of all smart phones that break before the warranty expires and about percent will not contain the true population proportion.

Question 2: In order to determine the miles per gallon rating for a new midsize minivan, an automaker randomly selected a sample of 50 vehicles. The showed = 31.56 mpg with s=.798 mpg. At 95% confidence, what is the minimum mpg rating you could give the car?
A magazine provided results from a poll of 500 adults who were asked to identify their favorite pie. Among the 500 respondents, 13% chose chocolate pie, and the margin of error was given as ±4 percentage poits. Describe what is meant by the statement that "the margin of error was given as ±4 percentage points." (...) Choose the correct answer below. OA. The statement indicates that the study is only 4% confident that the true population percentage of people that prefer chocolate pie is exactly 13%. OB. The statement indicates that the study is 100% -4% = 96% confident that the true population percentage of people that prefer chocolate pie is 13%. OC. The statement indicates that the interval 13% ± 4% is likely to contain the true population percentage of people that prefer chocolate pie. D. The statement indicates that the true population percentage of people that prefer chocolate pie is in the interval 13% ± 4%.
Ch. 6.1 CI We examine the effect of different inputs on determining the sample size needed to obtain a specific margin of error when finding a confidence interval for a proportion. Find the sample size needed to give, with 95% confidence, a margin of error with +/- 6% when estimating a proportion. Within +/- 4%. Within +/- 1%. (Assume no prior knowledge about the population proportion p). Comment on the relationship between the sample size and the desired margin of error.
Question 1: a) The mean volume of liquid in bottles of lemonade should be at least 2 liters. A sample of bottles is taken in order to test whether the mean volume has fallen below 2 liters.
