Problem #5: The breaking strength of yarn used in the production of woven carpet material is normally distributed. A randomsample of 5 specimens of yarn from a production run is measured for breaking strength, and the standarddeviation is found to be 2.9. Also, a confidence interval for the true mean breaking strength u is calculated to be(131.825166, 137.354834). What is the confidence level for this interval?Problem #5:answer as a percentagecorrect to 2 decimals, e.g., 82.50

How can we also find normality?
In an effort to estimate the mean amount spent per customer for dinner at a major Atlanta restaurant, data were collected from 64 randomly selected customers. The sample mean was calculated as $27.75 with a sample standard deviation of $4. We wish to develop a 91% confidence interval for the mean amount spent per customer for dinner at this restaurant. Assume that the standard deviation of the amounts spent by ALL customers is $4.30. What is the variable of interest? ["", "", ""] And is this variable Quantitative or Qualitative? ["", ""] In other words: what is the one piece of info we care about for each individual in the population? Is it a quantitative measurement? Or do we determine if each individual belongs to a certain category (referred to as success) or not (failure)? If it is a quantitative measurement, then the population is filled with numbers. Otherwise, the population is filled with…
Abe and Betty want to estimate the mean of a population with known standard deviation o. Abe takes 50 samples whereas Betty takes 80 samples. Which of the following statements are correct? (A) If both Abe and Betty use confidence intervals of the same width, then the confidence level of Abe's interval is smaller than that of Betty's (B) If both Abe and Betty use confidence intervals of the same width, then the confidence level of Abe's interval is larger than of Betty's (C) If Abe and Betty construct confidence intervals with the same confidence level, then the width of Abe's interval is smaller than that of Betty's (D) If Abe and Betty construct confidence intervals with the same confidence level then the width of Abe's interval is larger than that of Betty's (B) and (C). (A) and (D) (B) and (D) (A) and (C)
If the mean of a data set is 12.3 and the standard deviation is 0, then a. all the observations are equal to 12.3 b. there must have been a mistake in the calculation, as it is not possible to have a standard deviation of 0 c. a histogram of the data set has a single peak at zero d. a histogram of the data set will be strongly skewed e. there is a large amount of variabitilty in the data set
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.
Suppose we have data coming from 69 i.i.d) observations. The sample mean is JÓ28 and the sample standard deviation is calculated to be 1.63. Find a 95% confidence interval for the true mean.
An advertiser was about to launch an advertisement campaign for a new product. He conducted a random survey to find the preference for the new product among the respondents. Based on his previous experience, he found the standard deviation for the population as 4. Because the population mean was not known to him, he randomly selected 25 responses and found that the sample mean preference for the new product was 10. Which of the following parameters did he use to calculate a confidence interval at the 95% confidence level for this population mean? z0.10 z0.05 z0.025 z0.01 z0.005 1.282 1.645 1.960 2.326 2.576
An article in the San Jose Mercury News stated that students in the California state university system take 4.5 years, on average, to finish their undergraduate degrees. Suppose you believe that the mean time is longer. You conduct a survey of 43 students and obtain a sample mean of 5.1 with a sample standard deviation of 1.2. Do the data support your claim at the 1% level?Note: If you are using a Student's t-distribution for the problem, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.) a. What is the test statistic? (If using the z distribution round your answer to two decimal places, and if using the t distribution round your answers to three decimal places) b.What is the p-value? Explain what the p-value means. c. Construct a 95% confidence interval for the true mean. Sketch the group of the situation. Label the point estimate and the lower and upper bounds of the confidence interval.
