Suppose a new product is to be launched on the market. To gain an idea of the potential market size, a sample of people selected at random are to be shown the product and asked if they would be willing to buy it. A 90% confidence interval for the proportion of all people who would buy the product will then be calculated based on the realized sample proportion of these people who would be willing to buy the product. In this case the largest sample size that would be required to allow us to be 90% confident that the realized sample proportion is within 0.02 of the true population proportion of all people who would be willing to buy the product is (rounded up to the nearest integer)

Suppose you want to estimate the proportion of employed adults who would continue working if they won $10 million in the lottery. A previous study on the issue of how to sample proportion of 0.59. How many employed adults should be randomly sampled in order to get a 99% confidence interval with a width of 0.3?
QUESTION 1 Suppose a sample of 200 local vendors is selected as part of a survey conducted by the Ministry of Trade and it is found that 145 of the local vendors make an average income in excess of $ 7 600 per month. a) Suppose that a 97% confidence interval estimate of the proportion of local vendors who make an average income less than N$ 7 600 per month is required. How large a sample should be taken if the desired margin of error is 5%? b) Suppose it has been established from past studies that 75% of local vendors make an average income in excess of N$ 7 600 per month. Use the p-value approach and conduct a hypothesis test at a 1% level of significance to determine whether the proportion of local vendors who make an average income in excess of N$ 7 600 per month differs from the historical level?
You want to estimate the difference between two population proportions using an 80% confidence interval. You need to take samples that are large enough, so that the width of the confidence interval does not exceed 5.0%. You wish to take two samples (one from each population) of the same size n. The populations have not been sampled before, and therefore you have no information about what the two proportions may be. Using the most conservative estimates for the two population proportions, what is the minimum sample size you will need (for both of the samples)? (Round the result up to the nearest integer.)

1. In a study of perception, 110 men are tested and 24 are found to have red/green color blindness (based on data from USA Today). Assume that this was done in a simple random manner. A 95% confidence interval estimate of the proportion of all men with red/green color blindness was found to be 0.14 to 0.30. If we learn that the actual population proportion of men with red/green colorblindness is equal to 0.12, then what can we conclude? A. The confidence interval was wrong. B. We would need to see the sample data to make any conclusions Pick either answer A or B as your answer and show your work to go with it
suppose that you take 1000 simple random samples from a population and that, for each sample, you obtain a 95% confidence interval for an unknown parameter. Approximately how many of those confidence intervals will continue the value of the unknown parameter?
QUESTION 23 Ali constructed a 98% confidence interval for the mean amount spent per day in a shopping mall based on 100 customers. The confidence interval was found to be (AED 1150, AED 2150). Select all correct answers. The mean amount spent per day by the 100 customers selected in the sample falls between AED 1150 and AED 2150. We are 98% confident that the mean amount spent per day by customers falls between AED 1150 and AED 2150. The mean amount spent per day by all customers falls between AED 1150 and AED 2150. 98% of all customers spent between AED 1150 and AED 2150 per day.
What is meant by the term “90% confident” when constructing a confidence interval for a mean? If we took repeated samples, approximately 90% of the samples would produce the same confidence interval. If we took repeated samples, approximately 90% of the confidence intervals calculated from those samples would contain the sample mean. If we took repeated samples, approximately 90% of the confidence intervals calculated from those samples would contain the true value of the population mean. If we took repeated samples, the sample mean would equal the population mean in approximately 90% of the samples.
I'm having trouble trying to figure out how to work the problem below out. Let’s say that 44 percent of the 1,300 U.S. adults who responded to a poll about marijuana legalization said they support legalization. Let’s also say the margin of error for the results is +/- 3 percentage points. The margin of error tells us there’s a high probability that nationwide support for marijuana legalization falls: The correct interpretation of this confidence interval is:
Ellie and Alec are each attempting to estimate the proportion of coffee drinkers who consume more than one cup of coffee per day. They each obtain a random sample of coffee drinkers, and, in each sample, the proportion who drink more than one cup of coffee per day is 0.40. Ellie and Alec each use their sample data to construct a confidence interval. Ellie’s interval is from 0.286 to 0.514, and Alec’s interval is from 0.346 to 0.474. One of these intervals was computed correctly, but the other was not. Which interval must be incorrect? A. Ellie’s interval must be incorrect. B. Alec’s interval must be incorrect. C. It’s impossible to answer this question without knowing the level of confidence used for each interval. D. It’s impossible to answer this question without knowing the sample sizes. E. It’s impossible to answer this question without knowing the sample sizes or the level of confidence used for each interval.
