The mean score of Grade 11 students in a General Math examination was observed to be 75 with a standard deviation of 5. The teacher wants to replicate the study to estimate the true population mean to within 0.3 maximum error. If the 90% level of confidence is adopted, how many respondents are needed?
A researcher collected sample data for 17 women ages 18 to 24. The sample had a mean serum cholesterol level (measured in mg/100 mL) of 188.4, with a standard deviation of 9.2. Assuming that serum cholesterol levels for women ages 18 to 24 are normally distributed, find a 90% confidence interval for the mean serum cholesterol level of all women in this age group. Then find the lower limit and upper limit of the 90% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place.
A firm is looking to employ a person as an engineer. Applicants of earlier years have standart deviation of 35.8. we pick random 75 people who apply to job this year and their mean result of the exam is 167.5. What is the 90 percent confidince interval for the mean of all applicants exam results?
Noise levels at various area urban hospitals were measured in decibels. The mean of the noise levels in 81 corridors was 62.04 decibels, and the standard deviation of the population was 6.34. Find the upper boundary of the 95% confidence interval of the true mean. Only the final answer should be rounded-off to TWO decimal places.
The mean diastolic blood pressure for a random sample of 70 people was 96 millimeters of mercury. If the standard deviation of individual blood pressure readings is known to be 11 millimeters of mercury, find a 90% confidence interval for the true meandiastolic blood pressure of all people. Then give its lower limit and upper limit.
A recent survey of 10 social networking sites has a mean of 12.67 million visitors for a specific month. The standard deviation was 3.3 million. Find the 95% confidence interval of the true mean. Assume the variable is normally distributed. Use a graphing calculator and round the answers to at least one decimal place. <μ<
A survey taken several years ago found that the average time a person reading a newspaper was 10.8mins. The standard deviation was 3mins. To see whether the average time changed since the newspapers format was revised, the editor survered 36 individuals. The average time the 36 people spent reading the paper was 12.2mins. At $=0.02, is there a change in the average time an individual spends reading the paper ? Find the 98% confidence interval of the mean.
A veterinarian wants to estimate the mean weight of a cat in their city. They take a random sample of 19 cats and found a mean of 10.9 lbs with a sample standard deviation of 1 lbs. Find the 95% confidence interval of the mean. Assume that the cat weights are normally distributed. Do not round in between steps. Round answers to at least 4 decimal places.
Find the lower limit of 95% confidence interval. An SRS of 36 students were taken from high schools in a particular state. The average test score of the sampled students was 60 with a standard deviation of 13.26. Give the lower limit of the interval approximation.
The length of a doohickey is normally distributed with a standard deviation of 8 inches. If a random sample of 16 doohickeys has an average length of 30 inches find a 96% confidence interval for the mean of the lengths of the doohickeys.
On a measure of running speed on a 100 meter dash, students received timed scores ranging from 12 seconds to 24 seconds. The distribution of running times is normative with a mean of 16 seconds. Transferring this ratio data to standard scores for comparison with the results of classes from other departments, the mean score is assigned a standard score of 100 with a standard deviation of 10. From this example, a standard score of 99 would mean the actual value in seconds for an individual would be about a. 16 b. 12 c. 19 d. 24
The president of a large university wishes to compare the standard deviation of the ages of students presently enrolled to previous years. The distribution of ages has been approximately normal. Find the 90% confidence interval for the population standard deviation of the student ages of the University. A random sample of 20 university students has a standard deviation of 6.1 years in a mean of 23.8 years what is the confidence interval of the population standard deviation?
