Aspirin is packed in 120 tab bottles with weight normally distributed with mean 600g and standard deviation 6g. Rejected bottles are those whose weight differs from the mean weight by 15g or more. That is, rejected bottles have weight either too small or too large. We want to find out how many bottles will be rejected from a daily production of 5000 bottles. 1,Do we have to calculate one z-score or two z-scores? 2. The negative z-score is 3. The positive z-score is 4.How many bottles, of the 5000, do we anticipate to have to reject?

In a poll, 1000 adults in a region were asked about their online vs. in-store clothes shopping. One finding was that 37% of respondents never clothes-shop online. Find and interpret a 95% confidence interval for the proportion of all adults in the region who never clothes-shop online. Click here to view page 1 of the table of areas under the standard normal curve. Click here to view page 2 of the table of areas under the standard normal curve. The 95% confidence interval is from to. (Round to three decimal places as needed.) Interpret the confidence interval. Choose the correct answer below. A. There is a 95% probability that the sample proportion of a survey that asks adults in the region whether they clothes-shop online will be within the bounds of the confidence interval found in the previous step. B. With 95% confidence, the true percentage of all adults in the region who never clothes-shop online is within the bounds of the confidence interval found in the previous step. C. With…
