A group of adult males has foot lengths with a mean of 28.43 cm and a standard deviation of 1.13 cm. Use the range rule of thumb for identifying significant values to identify the limits separating values that are significantly 25.7 cm significantly low or significantly high? Explain. Significantly low values are cm or lower. (Type an integer or a decimal. 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. O A. The adult male foot length of 25.7 cm is significantly high because it is greater than cm (Type an integer or a decimal. Do not round.) O B. The adult male foot length of 25.7 cm is not significant because it is between (Type integers or decimals. Do not round.) cm and O C. The adult male foot length of 25.7 cm is significantly low because it is less than cm (Type an integer or a decimal. Do not round.) cm C or significantly high. Is the…

A rugby team from the country of Atlantis is formed by randomly drawing from its population. The population distribution is normally distributed with a mean of 165 cm and a standard deviation of 10 cm. The team draws 26 people for the team. Given a population mean of 165cm, how many standard deviations would a sample mean of 163cm be from the true value? Give your answer rounded to two decimal places.
