01 Confidence Interval Mistakes and MisunderstandingsQ1.1 Computes 99% IntervalSuppose that 40 randomly selected Mexican free-tail bats were selected and weighed. The samplemean weight was found to be 12.5 grams. Assume that the population standard deviation isknown to be 1.1 grams.Someone computes the 99% confidence interval for the average weight of a Mexican free-tail batas 12.5 2.576(1.1). What is the mistake of this student? (Be brief!)Save AnswerQ1.2 States "I am 99% Confident"After correcting the mistake in part (1.1), the student states "I am 99% confident that the samplemean weight is between 12.052 and 12.948 grams." What is wrong with this statement? (Be brief!)Save AnswerQ1.3 "Probability that true mean..."The student quickly realizes the mistake made in part (1.2) and now says "The probability that thetrue mean weight is between 12.052 and 12.948 grams is 99%." What misinterpretation is thestudent making now? (Be brief!)Save AnswerQ1.4 Defends use of Normal DistributionFinally, to defend the use of the Normal distribution to calculate the confidence interval the studentsays, "Because the sample size is quite large, the population of weights will be approximatelyNormal." Correct this misunderstanding. (Be brief!)

Suppose a certain species bird has an average weight of x = 3.2 grams. Based on previous studies we can assume that the weights of these birds have a normal distribution with sigma = 0.34 grams. For a small group of 18 birds , find a 98% confidence interval for the average weights of these birds. Write answer in interval notation with two decimal places.
An auditor takes a random sample of 880880 invoices from the 9510 invoices relating to the activities of a company in 2019. The sample mean value of the sampled invoices was £126 and the sample standard deviation was £58. Find a 99% confidence interval for the mean value of all the invoices for 2019. Round to 3 decimal places The records of the company states that the total income from the 9510 invoices was £1150710. The auditor's sample evidence does not support this stated total. True or false? What is the probability, rounded to 3 decimal places, that the company's income does not exceed the value in the records?
A researcher is interested in examining whether the location that a person lives is related to the number of hours that they spend on the internet each week. The researcher collected data from a sample of 30 participants who were classified in one of three groups: (1) 10 people who live in an urban setting, (2) 10 people who live in a suburban setting, and (3) 10 people who live in a rural setting. Each participant reported the number of hours they spend on the internet in a typical week (the dependent variable). The researcher found the following descriptive statistics: Urban participants reported an average of 8.9 hours of internet use per week with a standard deviation of 2.77. Suburban participants reported an average of 12.7 hours of internet use per week with a standard deviation of 4.88. Rural participants reported an average of 9.8 hours of internet use per week with a standard deviation of 2.82. Using the data that was collected, the researcher found the following: The…
9a) Researchers obtained the body temperature of 52 healthy humans and found the average body temperature of these 52 people to be 98.4°F. Construct a 90% confidence interval for the population mean body temperature of healthy humans. Assume the population standard deviation is 0.97°F. Interpret your result.
Prof. Gersch knows that the score on a standardized test is perfectly normal with unknown mean and a standard deviation of 50. He then takes a random sample of 25 tests and finds that the average of these is 200. How many exams should he sample so that the maximum margin of errorfor his 95% confidence interval is 10?: a. 98 b. 97 c. 100 d. 96 e. 10
The Florida Department of Transportation (FDOT) would like to estimate the average speed of vehicles on 95. The mean speed , in miles per hour , of a random sample of vehicles was found to be 73 miles per hour. The standard deviation of the speeds of all vehicles on 1 - 95 is known to be 15 miles per hour . Find three different confidence intervals one with sample size 103, one with sample size 231, and one with sample size 370. Assume that the mean of each sample is 73 miles per hour . Notice how the sample size affects the margin of error and the width of the interval. Report confidence interval solutions using interval notation . Round solutions to two decimal places, if necessary .
Suppose the mean height in inches of all 9th grade students at one high school is estimated. The population standard deviation is 3 inches. The heights of 7 randomly selected students are 72, 61, 74, 68, 64, 66 and 64. x¯ = Margin of error at 95% confidence level = 95% confidence interval = [ , ]
An agronomist would like to estimate the average weight of all Indian River County oranges. The mean weight of a random sample of 115 Indian River County oranges was found to be 129 grams. The standard deviation of the weights of all Indian River County oranges is known to be 17 grams. Find three different confidence intervals - one with a 99% confidence level, one with a 95% confidence level, and one with a 90% confidence level - for the mean weight of all Indian River County oranges. Notice how the confidence level affects the margin of error and the width of the interval. Report confidence interval solutions using interval notation. Round solutions to two decimal places, if necessary. The margin of error for a 99% confidence interval is given by E = A 99% confidence interval is given by
