The brain volumes (cm3) of 50 brains vary from a low of 908 cm3 to a high of 1478 cm3. Use the range rule of thumb to estimate the standard deviation s and compare the result to the exact standard deviation of 174.7 cm3, assuming the estimate is accurate if it is within 15 . The estimated standard deviation is nothing cm3. (Type an integer or a decimal. Do not round.) Compare the result to the exact standard deviation. 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 accurate because the error of the range rule of thumb's approximation is less than 15 cm3. C. The approximation is not accurate because the error of the range rule of thumb's approximation is less than 15 cm3. D. The approximation is accurate because the error of the range rule of thumb's approximation is greater than 15 cm3.

Doggie Nuggets Inc. (DNI) sells large bags of dog food to warehouse clubs. DNI uses an automatic filling process to fill the bags. Weights of the filled bags are approximately normally distributed with a mean of 49 kilograms and a standard deviation of 1.84 kilograms. DNI is unable to adjust the mean of the filling process, However it is able to adiust the standard deviation of the filling process. What would the standard deviation need to be so that no more than 10% of all filled bags weigh more than 54 kilograms? (Round to three decimal places as needed)
In a certain city, a researcher wishes to determine whether the average age of its citizens is really 61.2 years. A sample of 22 residents has an average age of 59.8. The standard deviation of the sample is 1.5 years. At 0.01, is the average age of the residents really 61.2 years? Assume that the variable is approximately normally distributed.

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2500 grams and a standard deviation of 800 grams while babies born after a gestation period of 40 weeks have a mean weight of 3000 grams and a standard deviation of 385 grams. If a 32-week gestation period baby weighs 2650 grams and a 41-week gestation period baby weighs 3150 grams, find the corresponding z-scores. Which baby weighs more relative to the gestation period? Find the corresponding z-scores. Which baby weighs relatively more? Select the correct choice below and fill in the answer boxes to complete your choice. (Round to two decimal places as needed.) A. The baby born in week 41 weighs relatively more since its z-score, nothing, is smaller than the z-score of nothing for the baby born in week 32. B.

Hawaiians are known to have an active lifestyle, enjoying the fresh air and natural beauty the islands have to offer. The life expectancy of the US population across all 50 states is µ=78.62 years with a standard deviation σ=16.51 years. A randomly selected sample of 100 Hawaiians show an average life expectancy x̅=82.52 years. Is Hawaiians’ average life expectancy significantly different from 78.62, assuming α=0.01?
