3. ABC hospital with branches in lloilo City and in Bacolod City has developed an improvedprocess for serving patients during noon to 1 PM lunch period. The waiting time of all thepatients during this hour is recorded over a period of one week. A random sample of 15patients from lloilo City and 14 patients in Bacolod City yielded the following statistics (inminutes):At df = 27, t-test tabular value = 2.771BranchMean SDIloilo CityBacolod City| 7.111.642.084.29Is there an evidence of a difference in the average waiting time between twobranches at 1% level of significance?А.

Unfortunately, arsenic occurs naturally in some ground water. A mean arsenic level of µ = 8 parts per billion (ppb) is considered safe for agricultural use. A well in Los Banos is used to water cotton crops. This well is tested on a regular basis for arsenic. A random sample of 37 tests gave a sample mean of - = 7.3 ppb arsenic. It is known that o = information indicate that the mean level of arsenic in this well is less than 8 ppb? Use the classical 1.9ppb for this type of data. Does this approach. Use a = 0.01 What is the criterion (step 3) for this problem? 2.33 or more 1.645 or more -2.33 or less -1.645 or less
A coin-operated coffee machine made by BIG Corporation was designed to discharge a mean of eight ounces of coffee per cup. If it dispenses more than that on average, the corporation may lose money, and if it dispenses less, the customers may complain.BIG Corporation would like to estimate the mean amount of coffee, μ, dispensed per cup by this machine. BIG will choose a random sample of cup amounts dispensed by this machine and use this sample to estimate μ. Assuming that the standard deviation of cup amounts dispensed by this machine is 0.42 ounces, what is the minimum sample size needed in order for BIG to be 90% confident that its estimate is within 0.07 ounces of μ? Carry your intermediate computations to at least three decimal places. Write your answer as a whole number (and make sure that it is the minimum whole number that satisfies the requirements).

Should there be a significant difference with this study, what post-hoc test shall be used? Dr. Hess has done work that suggests that emotional arousal affects pupil size. To ascertain if the type of arousal makes a difference, you decided to measure pupil size under three different arousal conditions (Neutral, Pleasant, Aversive). Each participant will look at all the different pictures that differ according to the condition. The pupil size after viewing each photograph is measured in millimeters. * t-Test paired two sample for means O t-Test assuming equal variances O t-Test assuming unequal variances

The article "Well-Fed Crickets Bowl Maidens Over"† reported that female field crickets are attracted to males that have high chirp rates and hypothesized that chirp rate is related to nutritional status. The chirp rates for male field crickets were reported to vary around a mean of 60 chirps per second. To investigate whether chirp rate is related to nutritional status, investigators fed male crickets a high-protein diet for 8 days and then measured chirp rate. The mean chirp rate for the crickets on the high-protein diet was reported to be 101 chirps per second. Is this convincing evidence that the mean chirp rate for crickets on a high-protein diet is greater than 60 (which would then imply an advantage in attracting the ladies)? Suppose that the sample size and sample standard deviation are n = 32 and s = 40. You can test the relevant hypotheses to answer this question. A significance level of ? = 0.01 will be used. a) State the null and alternative hypotheses. H0: ? =…
A clinical trial is run to investigate the effectiveness of an experimental drug in reducing preterm delivery to a drug considered standard care and to placebo. Pregnant women are enrolled and randomly assigned to receive either the experimental drug, the standard drug or placebo. Women are followed through delivery and classified as delivering preterm (< 37 weeks) or not. The data are shown below. Is there a statistically significant difference in the proportions of women delivering preterm among the three treatment groups? Run the test at a 5% level of significance. Give each of the following 1) the appropriate null and alternative hypotheses; 2) the appropriate test; 3) the decision rule; 4) the calculation of the test statistic; and 5) your conclusion including a comparison to alpha or the critical value. Preterm Delivery Total Yes No Experimental Drug Standard Drug Placebo Total 33 40 32 45 13 18 17 35 37 83 120

A coin-operated coffee machine made by BIG Corporation was designed to discharge a mean of eight ounces of coffee per cup. If it dispenses more than that on average, the corporation may lose money, and if it dispenses less, the customers may complain. BIG Corporation would like to estimate the mean amount of coffee, H, dispensed per cup by this machine. BIG will choose a random sample of cup amounts 00 dispensed by this machine and use this sample to estimate H. Assuming that the standard deviation of cup amounts dispensed by this machine is 0.43 ounces, what is the minimum sample size needed in order for BIG to be 95% confident that its estimate is within 0.07 ounces of µ? Carry your intermediate computations to at least three decimal places. Write your answer as a whole number (and make sure that it is the minimum whole number that satisfies the requirements). (If necessary, consult a list of formulas.)
In our ANOVA calculation, we want our within-group variation to be higher than the between-group variation. True or False?
A farmer wishes to estimate the mean number of farm fires reported each weekend atMuscat area. From a sample of 50 weekends, the farmer found 2 weekends with 7 fires ,18weekends with 9 fires, 16 weekends with 10 fires, and the reminder with 11 reported fires. Thefarımer wants to check whether the average number of farm fires per weekend has changed due tothe new "fire control program" he helped developed last year. The average number of firs perweekend prior to the development of that program was 11.5i.Based on the information collected by the farmer ,test the farmersclaim that the number of farm fires has changed due to the program. Using aone-sided test at the 5% significance levelii) What is the P- value for your test
