For the NHANES weight data, do the followmg. (Round your answers to two decimal places.) (a) Calculate the unbiased estimate for the mean (in kg) using sample data. i k9 (b) Calculate the unbiased estimate for the standard dewation (in kg) using sample data. i k9 Given the proposed guideline for the maximum dosage in a 24-hour period for the new drug, the cutoff weight, in kilograms, necessary to avoid experiencing adverse symptoms is as follows. 4,000 mg 7 = 32 kg 125 mg/kg Assuming that your unbiased estimates for the population mean and standard dewation are accurate, calculate the Itscore for this cutoff weight. (Round your answer to two deCIrnal places.) Assuming that the population of weights of 12-year-old children in the us is normally distributed, use your z-score from the previous question to estimate the following. (a) Estimate the proportion 0f12cyearcold children who would exceed 125 mg of drug/kg of body weight when taking the maximum dose, (Round your answer to four decimal places.) (b) There are approximately four million lZ-yearolds in the us. Approximately how many of them would be at risk of experiencing adverse symptoms if they took the max dose of the new drug? (Round your answer to the nearest whole number.) Plot and upload a histogram of the data. (Submit a file with a maximum size of 1 Mia.) Choose File No me chosen This answer has not been graded yet. (a) Based on your plot, do you believe that the weights or children are normally distributed? ls\\ This answer has nol been graded yet. to) Another way to test for normality is to use percentages from the empirical rule. Compute the actual percentage of children whose weight rails Within 1, z, and 3 standard deviations of the mean and compare to the expected number (which assumes the data is normal).
