A simple random sample of size n=200 individuals who are currently employed is asked if they work at homeat least once per week. Of the 200 employed individuals surveyed, 41 responded that they did work at home atleast once per week. Construct a 99% confidence interval for the population proportion of employed individualswho work at home at least once per weekThe lower bound iswww(Round to three decimal places as needed)The upper bound is (Round to three decimal places as needed.)

We have given that, Favourable cases (x) = 41 and sample size (n) = 200 Then, We will find 99%…

Estimate and report the number of meals you eat out per week. Assume the standard deviation is known to be two meals. Let’s construct an approximate 95% confidence interval for the true mean number of meals a class of 10 eats out per week. Also, put this in a tabular format.
The distance a basketball player runs during a game is one of the many variables used for assessing the performance of the players. 76 players are followed for a game each and the average distance ran by them is found to be 3503 meters (m) with a standard deviation of 144 m. Then the lower limit for the 95% confidence interval for the true mean is Blank and the upper limit is blank . Fill in the blanks
A random sample of 169 New Englanders revealed that 154 wear a mask when they are indoors and not in their home. Find and interpret a 95% confidence interval for the proportion of New Englanders who wear a mask. Round your final answer to 2 decimal places. We are 95% confident the proportion of New Englanders that wear a mask is between _______% and ______ %. Please show all work showing how you got the answer so i can better understand thank you!
Sam computed a 95% confidence interval for mean from a specific random sample. His confidence interval was 10.1< mean< 12.2. He caims that the probability that mean is in this interval 0.95. What os wrong with his claim?
A random sample of 500 males included 215 that approved of the performance of a President. A random sample of 500 females included 185 that approved of the performance of a President.

The newest model of a car battery from a popular brand is supposed to have a lifetime of 60 months, but the lifetime varies slightly from battery to battery. It is known that the population of all lifetimes (in months) of this model of car battery is approximately normally distributed. You are a product reviewer who wants to estimate the standard deviation for this population with a random sample of 22 car batteries. Follow the steps below to construct a 99% confidence interval for the population standard deviation of all lifetimes of this model of car battery. (If necessary, consult a list of formulas.)

One scientist wondered if there was a difference in the average daily intake of dairy products between men and women. He took a sample of n1 = 50 adult men and n2 = 50 adult women and recorded their daily intake of dairy products in grams per day. A summary of the sample results is presented in the table. Construct a 95% confidence interval for the difference in the average daily intake of dairy products for men and women. Can it be concluded that there is a difference in the average daily intakes for men and women?

A researcher was interested in comparing weekly salaries between men and women. Independent samples were drawn to find the average salary for each group. A 90% confidence interval for the difference between female and male employees was determined to be (-$110, $10) in a given week. Interpret the confidence interval Zero is contained in the interval so the probability that male employees earn the same as females is 0.9. 90% of the time, women earn less than men. ore per ek Based on these data, we would assume that female employees average between $110 and $10 than male employees O We are 90% confident that men earn between $110 less or $10 more than women in a given week.
The manager of a fleet of automobiles is testing two brands of radial tires and assigns one tire of each brand at random to the two rear wheels of eight cars and runs the cars until the tires wear out.
