The brain volumes (cm) of 20 brains have a mean of 1061.8 cm and a standard deviation of 126.1 cm. Use the given standard deviation and the range rule of thumb to identify the limits separating values that are significantly low or significantly high. For such data, would a brain volume of 1324.0 cm be significantly high? Significantly low values are cm³ or lower. (Type an integer or a decimal. Do not round.)

A group of adult males has foot lengths with a mean of 28.07 cm and a standard deviation of 1.42 cm. Use the range rule of thumb for identifying significant values to identify the limits separating values that are significantly low or significantly high. Is the adult male foot length of 25.0 cm significantly low or significantly high? Explain. Significantly low values are cm or lower. (Type an integer or a decimal. Do not round.)
The brain volumes (cm°) of 20 brains have a mean of 1119.5 cm° and a standard deviation of 122.2 cm°. Use the given standard deviation and the range rule of thumb to identify the limits separating values that are significantly low or significantly high. For such data, would a brain volume of 1343.9 cm° be significantly high? cm° or lower. Significantly low values are (Type an integer or a decimal. Do not round.)
The manager at UPS feels that the weights of packages shipped recently are less than in he past. Records show that in the past packages have had a population mean weight of 36.7 pounds and a population standard deviation of 14.2 pounds. A random sample of last month's shipping records yielded a sample mean weight of 32.1 pounds for 64 packages. Does this indicate that the weights of packages recently shipped is less than 36.7 pounds? Use a = 0.01. Use the Classical Approach.

A vendor converts the weights on the packages she sends from pounds to kilograms (1 kg ≈ 2.20 lb). The mean weight of the package was 21 lb with standard deviation of 0.31 lb. After repackaging (converting units), the mean becomes kg (round your answer to 2 decimal places), and the standard deviation becomes kg (round your answer to 2 decimal places).
