A worm in my apple-Codling moths are a devastating insect pest for apples. Each spring, adult moths lay their eggs on or around developing appies. When the eggs hatch the larva, or wom, tunnels into the apple, where theyfeed on the fruit and develop for three to five weeks.Cain has developed a scanning machine to detect the presence of larvae in appies. If the apple is infested with larvae, the machine reports a positive result 84.3% of the time. If the apple is not infested, the machine reports anegative result 64.6% of the timeRound all answers to 4 decimal places1. Suppose that 8.2% of apples in an orchard are infested with larvae. Assume a theoretical population of 10,000 apples and construct the contingency table for this scenarioTest NegativeInfestedNot infestedTotalTest Positive2. What proportion of apples will test positive for larvae infestation?3. What proportion of apples that test positive for larvae infestation would we expect to not actually be infested with larvae?Total10,000

An article in Quality Engineering presents viscosity data from a batch chemical process. A sample of these data is in the table. Reading left to right and up to down, draw a time series plot of all the data and comment on any features of the data that are revealed by this plot. Consider that the first 40 observations (the first 4 columns) were generated from a specific process, whereas the last 40 observations were generated from a different process. Does the plot indicate that the two processes generate similar results? Calculate the sample mean and sample variance of the first 40 and the second 40 observations.

Suppose a two-tailed t-test is conducted to test for a difference between the population means of adult female stoach weights and adult male stoach weights. The female sample has 13 weights, and the male sample has 7 weights. The t-statistic for the test is -0.20542. What is the p-value? (Give your answer to 4 decimal places.) p-value:
Document (5) Saved Parents often wonder, usually out of sheer curiosity, how tall their child will be as an adult. When a child has a medical condition or appears to be growing abnormally, the need to under-stand his or her growth can be important. One early method involved simply doubling a child's height at age 2. This gave very inaccurate results, especially for girls. As a result, many better methods have been developed to try to accurately predict a child's eventual adult height from various factors. 1. One simple method to predict adult height is to average the parents' heights and then add 2.5 inches if the child is a boy or subtract 2.5 inches it the child is a girl. This method can be fairly accurate, but can also be as much as 5 inches above or below the child's eventual height. Write a formula or formulas to express this calculation, and clearly define any variables that you use. 2. Another method is to add the parents' heights and then add an additional 5 inches if the…
