- Use the given data to find the 95% confidence interval estiate of the population mean ?μ. Assume that the population has a normal distribution. IQ scores of professional athletes:Sample size n=20Mean =106Standard deviation ?=9 ? <?< ?arrow_forwardUse the given degree of confidence and sample data to construct a confidence interval for the population mean μ. Assume that the population has a normal distribution. Thirty randomly selected students took the calculus final. If the sample mean was 76 and the standard deviation was 7.7, construct a 99% confidence interval for the mean score of all students.arrow_forwardConstruct the confidence interval for the population mean μ. c=0.98, x=7.7, σ=0.3, and n= 47 A 98% confidence interval for μ is ?arrow_forward
- Construct the confidence interval for the population mean μ. c=0.98, x=16.6, σ=7.0, and n= 70 A 98% confidence interval for μ is ?arrow_forwardThe shape of a given population distribution is normal with a mean of μ = 85 and a standard deviation of o= 6.5. For these parameters, transform a raw score of X = 100.5 into its corresponding z score. Round to the nearest tenths place if a fraction. The z score is: O 2.4 -3.7 -3.4 09.2 The correct z-score is not listed.arrow_forwardUse technology to construct the confidence intervals for the population variance of and the population standard deviation o. Assume the sample is taken from a normally distributed population. c=0.95, s=37, n= 18 The confidence interval for the population variance is (770 86, 3076.74). (Round to two decimal places as needed.) .... The confidence interval for the population standard deviation is (Round to two decimal places as needed.)

- You measure 43 backpacks' weights, and find they have a mean weight of 65 ounces. Assume the population standard deviation is 9.3 ounces. Based on this, construct a 95% confidence interval for the true population mean backpack weight.Give your answers as decimals, to two places______ ± ________ouncesarrow_forwardSuppose you take a random sample of n = 80 Douglas College students and ask each student their age. You find that the mean age of students in this sample is X = 22.0375 years and the sample standard deviation is s = 3.2014 years. Fill in the blanks (rounding to four decimal places): The 95% confidence interval for the mean age μ of all Douglas College students is from ______ years to ______ years.arrow_forwardWhat would be the correct way of doing this?arrow_forward
- A statistics class is estimating the mean height of all female students at their college. They collect a random sample of 42 female students and measure their heights. The mean of the sample is 65.3 inches and the sample standard deviation is 5.4 inches. Find the 90% confidence interval for the mean height of all female students in their school? Assume that the distribution of individual female heights at this school is approximately normal. 1. The t value is 1.3025 2. The standard error has a value of -- 3. The margin of error has a value of 4. Find the 90% confidence interval for the mean height of all female students in their schoolarrow_forwardAssume that population mean is to be estimated from the sample described. Use the sample results to approximate the margin of error and 95% confidence interval. Sample size, n = 100, sample mean, x= 72.0 cm; sample standard deviation, s = 4.0 cm The margin of error is (Round to one decimal place as needed.) cm.
