Assume the birth weights at a local hospital have a normal distribution with a mean of 110 oz and a standard deviation of 15 oz. Draw a normal curve and label the mean and each value which is one, two, or three standard deviations above the mean. Then label each value which is one, two, or three standard deviations below the mean.

Use the following information for the question. The average travel time to work for a person living and working in Kokomo, Indiana is 17 minutes. Suppose the standard deviation of travel time to work is 4.5 minutes and the distribution of travel time is approximately normally distributed.Which of these statements is asking for a measurement (i. e. is an inverse normal question)? A.What percentage of people living and working in Kokomo have a travel time to work that is between thirteen and fifteen minutes? B.If 15% of people living and working in Kokomo have travel time to work that is below a certain number of minutes, how many minutes would that be?
Help me find which A,B,C, or D is the correct answer to the last part please. The brain volumes (cm3) of 50 brains vary from a low of 904 cm3 to a high of 1490 cm3. Use the range rule of thumb to estimate the standard deviation s and compare the result to the exact standard deviation of 191.4 cm3, assuming the estimate is accurate if it is within 15 cm3. The estimated standard deviation is 146.5 cm3. A. The approximation is not accurate because the error of the range rule of thumb's approximation is greater than 15 cm3. B. The approximation is not accurate because the error of the range rule of thumb's approximation is less than 15 cm3. C. The approximation is accurate because the error of the range rule of thumb's approximation is greater than 15 cm3. D. The approximation is accurate because the error of the range rule of thumb's approximation is less than 15 cm3.
