Question

The lifetime X of a widget has a Weibull distribution with parameters a = 2 and B = 5.
The mean widget lifetime is E[X] = 4.43. The standard deviation of the lifetime is StDev(X) = 2.316.
What is the probability the widget lasts between 2.6 and 5.2? P( 2.6 < X < 5.2 ) =

Biological oxygen demand (BOD) is a pollution index that is monitored in the treated effluent of paper mills. A certain paper mill has taken 31 samples over the past 3 months. The mean and standard deviation for the sample data are 3.42 and 0.728 ppm respectively. The mill would like to see if this sample indicates that the true average BOD in their treated effluent exceeds the targeted 3.00 ppm. Let ? = 0.05. A) The test statistic, (ttest), for this data set is: Note: Round your answer to the nearest hundredth.B) The p-value is: C) The statistical decision and corresponding English interpretation for this study are: Fail to reject Ha: conclude that the true BOD in treated effluent exceeds 3 ppmFail to reject Ho: we cannot conclude that the true BOD in treated effluent exceeds 3 ppm Reject Ha: we cannot conclude that the true BOD in treated effluent exceeds 3 ppmReject Ho: conclude that the true BOD in treated effluent exceeds 3 ppm

Suppose the mean cholesterol levels of women age 45-59 is 5.2 mmol/l and the standard deviation is 0.7 mmol/l. Assume that cholesterol levels are normally distributed. Find the probability that a woman age 45-59 has a cholesterol level above 6.1 mmol/l (considered a high level). Round to four decimal places.P(x > 6.1) = Suppose doctors decide to test the woman’s cholesterol level again and average the two values. Find the probability that this woman’s mean cholesterol level for the two tests is above 6.1 mmol/l. Round to four decimal places.P(x̄ > 6.1) = Suppose doctors being very conservative decide to test the woman’s cholesterol level a third time and average the three values. Find the probability that this woman’s mean cholesterol level for the three tests is above 6.1 mmol/l. Round to four decimal places.P(x̄ > 6.1) =
10. Lasers can provide highly accurate measurements of small movements. To determine the accuracy of such a laser, it was used to take 49 measurements of a known quantity. The sample mean error was 25 um with a standard deviation of 80 µm. The laser is not properly calibrated if the mean error, µ, is statistically different from 0. а. Construct a 99% confidence interval for the mean error. b. Interpret your interval in context in a way that expresses more than just how confident you are. Determine the sample size necessary to reduce the margin of error to 12 um. Assume the standard deviation remains 80 µm. d. с. Conduct a hypothesis test to determine whether the mean error differs from 0 as follows: i. State the appropriate null and alternative hypotheses. Compute the appropriate test statistic. Use n = 49. Compute the P – value. Using only your P – value (a is unknown at this point), state your conclusion in context. Is there sufficient evidence at a = .05 that the laser is not…
