Use the F-scale measurements of tornadoes listed in the accompanying table. The range of the data is 4.0. Use the range rule of thumb to estimate the value of the standard deviation. Compare the result to the actualstandard deviation of the data, 1.1, assuming a difference of 0.3 or greater would mean a significant difference.E Click the icon to view the table of F-scale measurements......Using the range rule of thumb, the standard deviation is approximately(Type an integer or decimal rounded to one decimal place as needed.)Compare the result to the actual standard deviation.The estimated standard deviation isthe actual standard deviation. Thus, the estimated standard deviationV significantly different from the actual standard deviation.MacBookDIIDDF9000000F820F6F7F5F4F3escF1F2&$78.1245WE-RYQtabJKG# 3 11O 1002000O N O O 0 0 0 11403 01002O312 221 023 2222N213 3030.ㅇ1.PrintDoneMacBook000000DDF7F4F5F8

Listed in the data table are IQ scores for a random sample of subjects with medium lead levels in their blood. Also listed are statistics from a study done of IQ scores for a random sample of subjects with high lead levels. Assume that the two samples are independent simple random samples selected from normally distributed populations. Do not assume that the population standard deviations are equal. Complete parts (a) and (b) below. Click the icon to view the data table of IQ scores. a. Use a 0.05 significance level to test the claim that the mean IQ scores for subjects with medium lead levels is higher than the mean for subjects with high lead levels.

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.
