Use 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.
Calculate the z-score for the largest value and interpret it in terms of standard deviations. Do the same for the smallest value N: 50 Mean:28.766 SE Mean: 0.476 St.Dev: 3.369 Min: 21.300 Q1: 26.375 Median: 29.400 Q3: 31.150 Max: 35.100
Answer the blanks with ref highlighted marks. Use image two to determine the test procedure and p value
Assume that adults have IQ scores that are normally distributed with a mean of 96.2and a standard deviation 20.7. Find the first quartile Q1, which is the IQ score separating the bottom 25% from the top 75%. (Hint: Draw a graph.) The first quartile is ___.
Construct a confidence interval for the population mean. Assume that the population has a normal distribution. n= 30, x bar = 84.6, s=10.5, 90% confidence.
Use the given data to find the 95% confidence interval estimate of the population mean u. Assume that the population has a normal distribution. IQ scores of professional athletes: Sample size n = 30 Mean x = 106 Standard deviation s = 12
Blood glucose levels for obese patients have a mean of 100 with a population standard deviation of 15. A researcher thinks that a diet high in raw cornstarch will have a positive or negative effect on blood glucose levels. A sample of 30 patients who have tried the raw cornstarch diet have a mean glucose level of 140. Test the hypothesis that the raw cornstarch had an effect. What is the test statistic and the p-value? O z=-14.61, p-value=0 O t-14.61, p-value=0 O t-14.61, p-value=0 O z=14.61. p-value=0
The cheetah is the fastest land mammal and is highly specialized to run down prey. The cheetah often exceeds speeds of 60 miles per hour (mph) and is capable of speeds above 72 mph. The accompanying table contains a sample of the top speeds of 35 cheetahs. The sample mean and sample standard deviation of these speeds are 59.59 mph and 4.32 mph, respectively. A histogram of the speeds is bell-shaped. Complete parts (a) through (d) below. LOADING... Click the icon to view the top speeds of cheetahs. a. Is it reasonable to apply the empirical rule to estimate the percentages of observations that lie within one, two, and three standard deviations to either side of the mean? A. It is reasonable to apply the empirical rule. The data is quantitative and the histogram of the data is bell-shaped; therefore, the empirical rule applies. B. It is not reasonable to apply the empirical rule. The data is quantitative, but the value of k takes on values less than 1;…
Pulse Rates of Males Refer to Data Set 1 “Body Data” in Appendix B and use the pulse rates of males. a. Find the mean and standard deviation, and verify that the pulse rates have a distribution that is roughly normal. b. Treating the unrounded values of the mean and standard deviation as parameters, and assuming that male pulse rates are normally distributed, find the pulse rate separating the lowest 2.5% and the pulse rate separating the highest 2.5%. These values could be helpful when physicians try to determine whether pulse rates are significantly low or significantly high.
Use the given data to find the 95% confidence interval estimate of the population mean μ. Assume that the population has a normal distribution. Give your answers to 2 decimal places. IQ scores of professional athletes: Sample size n 25 Mean x = 104 Standard deviation s = 9 = <μ<
The distribution of heights in a population of women is approximately normal. Sixteen percent of the women have heights less than 62 inches. About 97.5% of the women have heights less than 71 inches. Use the empirical rule to estimate the mean and standard deviation of the heights in this population. Mean: K inches Standard Deviation: inches
