. A researcher collects a sample of 24 measurements from a population and wishes to find a 99% confidence interval for the population mean. What value should he use for t*? b. If he instead decides to use a 95% confidence interval, will the interval be wider or be narrower or stay the same? Why?
Here are summary statistics for randomly selected weights of newborn girls: n = 203, x = 31.2 hg, s = 6.7 hg. Construct a confidence interval estimate of the mean. Use a 98% confidence level. Are these results very different from the confidence interval 30.1 hg < μ < 33.1 hg with only 18 sample values, x = 31.6 hg, and s = 2.4 hg? What is the confidence interval for the population mean Μ? Are the results between the two confidence intervals very different?

Here are summary statistics for randomly selected weights of newborn girls: n=218, x=32.8hg,s=6.2hg. Construct a confidence interval estimate of the mean. Use a 90% confidence level. Are these results very different from the confidence interval 32.0hg <μ<33.4 hg with only 20 sample values, x=32.7hg, and s=1.8hg? What is the confidence interval for the population mean μ?_____hg <μ<___hg Are the results between the two confidence intervals very different?
It was found that in a sample of 90 teenage boys, 70% of them have received speeding tickets. What is the 90% confidence interval of the true proportion of teenage boys who have received speeding tickets? Given the above information, how many boys must be sampled to be within 2% of true proportion in a 90% confidence interval? b. If no information is given for the proportion, how many boys must be sampled?
In a sample of 55 electric motors, the average efficiency (in percent) was 85 and the standard deviation was 2. a) How many electric motors must be sampled so that a 95% confidence interval specifies the mean to within ±0.31? Round up the answer to the nearest integer. b) How many electric motors must be sampled so that a 99.5% confidence interval specifies the mean to within ±0.31? Round up the answer to the nearest integer.
Here are summary statistics for randomly selected weights of newborn girls: n=165, x=33.6 hg, s=6.2 hg. Construct a confidence interval estimate of the mean. Use a 98% confidence level. Are these results very different from the confidence interval 32.1 hg<μ<34.3 hg with only 18 sample values, x=33.2 hg, and s=1.9 hg? What is the confidence interval for the population mean μ? Are the results between the two confidence intervals very different?
For a population of normally distributed scores, μ = 155 and σ = 12, approximately what would be the 95% confidence interval of the population mean based upon a random sample of 16 scores with a mean of 140?
Under proper conditions, the test of H0 ∶ µ = 5 versus Ha ∶ µ ≠ 5 results in a P-value of 0.035. Which of the following are true? A. A 95% confidence interval for µ will include the value 5. B. A 99% confidence interval for µ will not include the value 5. C. A 99% confidence interval for µ will include the value 0. D. A 95% confidence interval for µ will not include the value 5. E. A 95% confidence interval for µ will include the value 0.
An automotive manufacturer wants to know the proportion of new car buyers who prefer foreign cars over domestic. In an earlier study, the population proportion was estimated to be 0.280.28. How large a sample would be required in order to estimate the fraction of new car buyers who prefer foreign cars at the 95%95% confidence level with an error of at most 0.030.03? Round your answer up to the next integer.
A researcher wants to estimate the mean height of all the blackberry bushes in cititon park. Based on a prior study, she assumes that the standard deviation of the heights of all the bushes is 17 cm. If she wants to make a 95% confidence interval for the mean with the margin of error of 5 cm, at least how many bushes should be included in her sample?
