The following is the age distribution of 1,000 persons working in a large industrial house: Age-group No. of persons Age-group No. of persons 20-25 30 45-50 105 25-30 160 50-55 70 2 30-35 210 55-60 60 200 35 40 180 60-65 40 40 45 145 Due to continuous heavy losses the management decides to bring down the strength to 30% of the present number according to the following scheme: (i) To retrench the first 15% from the lower group. (ii) To absorb the next 45% in other branches. (iii) To make 10% from the highest age group retire permanently, if necessary. Calculate the age limits of the persons retained and those to be transferred to other departments. Also find the average age of those retained. 000
S-adenosyl methionine (SAM-e) is a naturally occurring compound in human cells that is thought to have an effect on depression symptoms. Suppose that a researcher is interested in testing SAM-e on patients who are struggling with cancer. She obtains a sample of n = 20 patients and asks each person to take the suggested dosage each day for 4 weeks. At the end of the 4-week period, each individual takes the Beck Depression Inventory (BDI), which is a 21-item, multiple-choice self-report inventory for measuring the severity of depression. The scores from the sample produced a mean of M = 24.4 with a standard deviation of s = 6.02. In the general population of cancer patients, the standardized test is known to have a population mean of 27.2. Because there are no previous studies using SAM-e with this population, the researcher doesn't know how it will affect these patients; therefore, she uses a two-tailed single-sample t test to test the hypothesis. From the following, select the correct…
Q5: The theory that resistance by mosquitoes to an insecticide is due to a single dominant gene has been examined. Homozygous resistant mosquitoes were crossed with homozygous susceptible mosquitoes to give A heterozygous population. These were crossed to the homozygous susceptible population. Of this back cross progeny 465 were exposed to the insecticide, 264 died. Is the percentage killed significantly different to the percentage predicted by the model?

Example 5.1.7 A car-hire firm has two cars, which are hired out everyday. The number of demands for a car on each day is distributed as a Poisson distribution with mean 1.5. Calculate the proportion of days on which neither car is used and the proportion of days on which a demand cannot be met due to lack of cars [e15 = 0.2231].
