According to a 2009 Reader's Digest article, people throw away about 8% of what they buy at the grocery store. Assume this is the true proportion and you plan to randomly survey 166 grocery shoppers to investigate their behavior. What is the probability that the sample proportion does not exceed 0.16?

You want to obtain a sample to estimate a population proportion. Based on previous evidence, you believe the population proportion is approximately 68%. You would like to be 95% confident that your estimate is within 3.5% of the true population proportion. How large of a sample size is required? Do not round mid-calculation.

cant figure out where im going wrong .

A teacher asks 200 volunteers to compete a survey. Responses to the question "do you own a car" (yes or no) were recorded. Please explain why this is not a binomial distribution.

Statistics Canada conducts an annual survey to estimate the proportion of Canadians aged 20 - 24 years of age who are smokers. The most recent application of the Canadian Tobacco Monitoring Survey involved a random sample of n=496 Canadians aged 20 to 24 years of age. Each was asked for the smoking status. The number of 20 to 24 year-olds sampled who indicated they were smokers was 333.(a) Compute the sample proportion. Use at least four decimals in your answer.p^= __________ (b) Using your answer in (a), find a 97% confidence interval for pnow, the current proportion of 20 to 24 year old Canadians who are smokers, by Bootstrapping 1000 samples. Use the seed 3994 to ensure that R-Studio "randomly" samples the same "random" samples as this question will expect.You can do this by including the code, you can copy it into your R-Studio to bootstrap your samples.RNGkind(sample.kind = "Rejection");set.seed(3994);B=do(1000) * mean(resample(c(rep(1,333),rep(0,496-333)), 496));Use at least four…

The distances golf balls travel under laboratory testing conditions are normally distributed. The mean is 312 yards. The probability the golf ball travels further than 319 yards is 0.28. Find the probability a randomly selected golf ball travels between 305 yards and 319 yards. Express the answer as a decimal value rounded to the nearest hundredth.
