A group of adult males has foot lengths with a mean of 28.33 cm and a standard deviation of 1.46 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 31.6 cm significantly low or significantly high? Explain. Significantly low values are (Type an integer or a decimal. cm or lower. Do not round.) Significantly high values are cm or higher. (Type an integer or a decimal. Do not round.) Select the correct choice below and fill in the answer box(es) to complete your choice. The adult male foot length of 31.6 cm is not significant because it is between (Type integers or decimals. Do not round.) OA. C cm and O B. The adult male foot length of 31.6 cm is significantly low because it is less than cm. (Type an integer or a decimal. Do not round.) O C. The adult male foot length of 31.6 cm is significantly high because it is greater than (Type an integer or a decimal. Do not round.) cm. cm.

Please answer with explanation. I will really upvote

The frequency distribution was obtained using a class width of 0.5 for data on cigarette tax rates. Use the frequency distribution to approximate the population mean and population standard deviation. Compare these results to the actual mean u= $1.885 and standard deviation o = $1.115. E Click the icon to view the frequency distribution for the tax rates. The population mean is S (Round to three decimal places as needed.)

An agronomist measured the height of 134 canola plants. The mean height was 214 cm and the standard deviation was 16 cm. Calculate the standard error of the mean.

Draw by hand or in Excel fully labelled curves on a common scale to represent two sets of scores where: b. Mean = 50, Standard Deviation = 2, Mean = 50, Standard Deviation = 5. CUA
