Gas Price Intervals Use the data from exercise 11.8 and find Bonferroni-corrected intervals for all three comparisons assuming an overall confidence level of 95%, using an individual confidence level of 98.33%. Then state whether the means are significantly different based on whether the intervals capture 0 or not. Compare your conclusions with the conclusions in exercise 11.8.

Suppose that a random sample of 32 house cats yields a mean systolic blood pressure of 118 mmHg with a standard deviation from the sample of 16 mmHg. You will use the information provided to estimate the mean systolic blood pressure of all house cats at 90% confidence. Part A) State the conditions required to calculate this estimate AND comment on how they were met: Save Answer Q2.2 Mechanics In a clinical setting it may be prudent to take the blood pressure of cats. Suppose that a random sample of 32 house cats yields a mean systolic blood pressure of 118 mmHg with a standard deviation from the sample of 16 mmHg.

- Solve it correctly please. I will rate accordingly. I will rate with 4votes but need correct answer.arrow_forwardDevelop a 99% confidence interval of the difference between the mean annual cost of attending private and public collegesarrow_forwardTwo random samples of 30 individuals were selected. One sample participated in an activity which simulates hard work. The average breath rate of these individuals was 19 breaths per minute. The other sample did some normal walking. The mean breath rate of these individuals was 12. Find the 95% confidence interval of the difference in the breath rates if the population standard deviation was 4.2 for breath rate per minute. Use μ, for the mean breath rate of individuals stimulated with hard work. Round the answers to one decimal place.arrow_forward
- a laboratory tested 36 chicken eggs and found that the mean amount of the cholesterol was 230 mg with s = 20 mg. Find a 90% confidence interval for the true mean cholesterol content of an egg.arrow_forwardfill all blanks.arrow_forwardA 95% confidence interval for μA -μg is given by (-2.3, 4.5). What can we infer from this confidence interval? (A) This confidence interval implies that the mean for sample A is less than the mean for sample B. (B) This confidence interval implies that the mean for sample A is equal to the mean for sample B. (C) With 95% confidence, there is convincing statistical evidence that the mean for population A is less than the mean for population B. (D) With 95% confidence, there is convincing statistical evidence that the mean for population A is greater than the mean for population B. (E) There is not convincing statistical evidence that the mean for population A is different from the mean for population B at the 5% significance level.arrow_forward

She predicted the pH level of a glass of milk with a temperature of 8.45 degrees to be ŷ= 6.795 a)A 95% confidence interval for the mean pH of all milk with temperature 8.45 degrees is calculated to be (6.76, 6.83). Which of the following is the correct interpretation of this confidence interval? -The mean pH level for all glasses of milk having a temperature of 8.45 degrees is somewhere between 6.76 and 6.83, with 95% confidence. -The pH level for one glass of milk with a temperature of 8.45 degrees is somewhere between 6.76 and 6.83, with 95% confidence. -There is a probability of 0.95 that the mean pH level for this glass of milk with temperature 8.45 degrees is between 6.76 and 6.83. -95% of all glasses of milk with a temperature of 8.45 degrees have a pH level between 6.76 and 6.83. b)Suppose we have a glass of milk whose temperature is 8.45 degrees.
