Q6
Tina catches a 14-pound bass. She does not know the population mean or standard deviation. So she takes a sample of five friends and they say the last bass they caught was 9, 12, 13, 10, and 10 pounds. Find the t and calculate a 95% (α = .05) confidence interval.
9. A random sample of 25 statistics examinations was taken. The average score in the sample was 76 with a variance of 144. Assuming the scores are normally distributed, the 99% confidence interval for the population average examination score is a. 70.02 to 81.98 b. 69.82 to 82.18 C. 70.06 to 81.94 d. 69.48 to 82.52
Which of the following terms is added and subtracted to the sample mean in order to obtain a 90% confidence interval containing the population mean? 1.960 Vn 1.645o 1.645- 1.960o
The following data represent a random sample of five measurements from a normally distributed population: 7,4,2,5,7 a. Find 90% confidence interval for u. b. Find a 99% confidence interval for u.
A sample of 19 elements was used to construct a 99% confidence interval for the population variance, the chi-square value (s) used for this test are: Select one: a. 7.015 to 34.805 b. 7.633 to 36.191 O c. 6.844 to 38.582 d. 6.265 to 37.156 ge Next page ETIVITY NEXT ACTIVITY Jump to. Midterm 1
Use the order statistics approach to estimate a 90% confidence interval of 95.1% VaR for a sample size of n = 1000 observations drawn from a normal distribution with zero mean and variance one.
answer e,f,g The following random sample was selected from a normal distribution: 4, 6, 3, 5, 9, 3. d. Assume that the sample mean x and sample standard deviation s remain exactly the same as those you just calculated but are based on a sample of n = 25 observations rather than n = 6 observations. Repeat parts a–c. What is the effect of increasing the sample size on the width of the confidence intervals? e. Use Rejection region to test the null hypothesis that the mean of the population is 6 against the alternative hypothesis, ?<6. Use ? = .05. f. Use p-Value to test the null hypothesis that the mean of the population is 6 against the alternative hypothesis, ? ≠6. Use ? = .05.
