The Children's Hospital of Orange County (CHOC) recommends that children drink the number of 8-ounce cups of water equal to their age. This means that a five-year-old child should drink five 8-ounce cups of water each day (40 oz of water).Suppose a sample of 50 five-year-old children was randomly selected from all residents of Irvine, CA.Families of the children were asked to record their child's water consumption for two consecutivedays on a weekend and the average number of ounces of water over the two days was recorded asthe estimated daily water intake for each child. The study started in June and ended in August.Suppose you find that the average water intake of all five-year-olds in the sample is 37 ounces perday with a standard deviation of 4.5 oz.14. Based on the 95% Cl of (35.25193, 38.87857), which of the following values is plausible for a p-value?0.25050.850.950.002505

The control department of a light bulb manufacturer randomly picks 4400 light bulbs from the production lot every week. The records show that, when there is no malfunction, the defect rate in the manufacturing process (due to imperfections in the material used) is 1%. When 1.25%o or more of the light bulbs in the sample of 4400 are defective, the control unit calls repair technicians for service. Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of p, where p is the proportion of defective light bulbs in a sample of 4400 when there is no malfunction. (b) Find the standard deviation of p. (c) Compute an approximation for P(p N 0.0125), which is the probability that the service technicians will be called even though the system is functioning properly. Round your answer to four decimal places.

7.88 Aluminum cans contaminated by fire. A gigantic NW warehouse located in Tampa, Florida, stores approxi- mately 60 million empty aluminum beer and soda cans. Recently, a fire occurred at the warehouse. The smoke from the fire contaminated many of the cans with black- spot, rendering them unusable. A University of South Florida statistician was hired by the insurance com- pany to estimate p, the true proportion of cans in the warehouse that were contaminated by the fire. How many aluminum cans should be randomly sampled to estimate the true proportion to within .02 with 90% confidence?
In an experiment, two different species of flowers were crossbred. The resulting 217 flowers from this crossbreeding experiment were categorized by the color of the flower and the stigma. The table provides the study results. 1: Magenta flower with Green stigma 2: Magenta flower with Red stigma 3: Red flower 4: Red flower Flower Type with Green stigma with Red stigma Observed # Flowers 115 49 32 21 According to genetic theory, the four resulting flower types should follow the ratio of 9:3:3:1, that is, should follow the following population proportions of 0.5625, 0.1875, 0.1875, and 0.0625. The biologist is interested in assessing whether the distribution for flower type for the experiment matches these genetic theory rates. The hypotheses to be tested are Họ: P1 = 0.5625, p2 = 0.1875, P3 = 0.1875, p4 = 0.0625, where p; represents the proportion of flowers in the population in group i HA: at least one p; differs from the stated proportions
