Leandro wants to build a one-sample z interval with 98% confidence to estimate the proportion of light bulbs that arrive broken upon shipment to his store. He takes a random sample of 500 bulbs and finds that 25 arrived broken. What critical value z* should Leandro use to construct this confidence interval? Choose 1 answer: A z* = 1.96 B z* = 2.054 z* = 2.326 D. z* = 2.576

The Pizza Shop wanted to determine what proportion of its customers ordered only cheese pizza. Out of 80 customers surveyed, 15 ordered cheese pizza. They want a 99% confidence interval of the true proportion of customers who order only cheese pizza. Which type of confidence interval should we use here? a confidence interval for the mean using a table value from the standard normal distribution. a confidence interval for the mean using a table value from the t distribution. a confidence interval for a proportion using a table value from the standard normal distribution. a confidence interval for proportion using a table value from the t distribution.
Tina catches a 14-pound bass. She does not know the population mean or standard deviation. So she takes a sample of five friends and they say the last bass they caught was 9, 12, 13, 10, and 10 pounds. Find the t and calculate a 95% (α = .05) confidence interval.
If n=14, ¯xx¯(x-bar)=34, and s=4, construct a confidence interval at a 80% confidence level. Assume the data came from a normally distributed population.
A researcher is trying to estimate the population mean (μ) of anxiety based on his sample of n = 16 scores. His sample M = 58 and the s = 5.36. Construct the 95% confidence interval for μ.
A researcher wants to make a 95% confidence interval for the population mean. She wants the maximum error of estimate to be within 4.8 of the population mean. The population standard deviation is 18.65. What would be the sample size the yield a maximum error of estimate within 4.8 of the population mean?
Beth wants to determine a 99% confidence interval for the true proportion of high school students in the area who attend their home basketball games. How large of a sample must she have to get a margin of error less than 0.04? Assume we have no prior estimate of the proportion and want a conservative choice for the sample size. n =
Imagine that a researcher wants to compare the intelligence levels of Poodles to all dogs. He hypothesizes that Poodles will score differently than other dogs. He uses a standard test of dog intelligence in his study. The population of all dogs has a mean of μ = 100, and an SD of 15. He obtains a random sample of 500 Poodles and he finds that the mean intelligence score of the sample is 117. Is this a one- or two- tailed test? Write the Ho and Ha for this research question. What kind of statistic should be calculated to test the hypothesis? Compute that statistic by hand What should the researcher conclude? Write a blurb describing the results
Cesar wants to know what the expected weight of a loaf of bread for quality control purposes. Based on a sample of 14 loaves of bread, he finds a sample average of 400 grams with a sample standard deviation of 15 grams. What’s the confidence interval at 95%? What is it at 99.9%? What would the confidence intervals (for 95% and 99.9%) be if the sample average was based on 140 loaves instead of 14? Include the upper and lower bounds for each of the four intervals and be sure to include what you put into Excel to determine your answer. Round your answers to two decimal places.
