Question

A group of adult males has foot lengths with a mean of 26.98cm and a standard deviation of 1.41cm. Use the range rule of thumb to identify the limits separating values that are significantly low or significantly high. Is the adult male foot length of 23.9 cm significantly low or significantly high? Explain.

1. Significantly low values are ___ cm or lower (do not round)

2. Significantly high values are ___ cm or higher (do not round)

3. select the correct answer choice below and fill in the blank (do not round)

a. the adult male foot length of 23.9cm is not significant because it is between ___cm and ___cm

b. the adult male foot length of 23.9cm is significantly low because it is less than ___cm

c. the adult male foot length of 23.9cm is significantly high since its greater than ___cm

beats per minute. Use the range rule of thumb to identify the
limits separating values that are significantly low or
significantly high. Is a pulse rate of
142.5142.5
beats per minute significantly low or significantly high?
Significantly low values are
nothing
beats per minute or lower.

The brain volumes (cm cubed) of 20 brains have a mean of
1059.2 cm cubed and a standard deviation of 128.9 cm cubed. 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 1287.0
cm cubed be significantly high?

A certain group of test subjects had pulse rates with a mean of
83.4 beats per minute and a standard deviation of 11.5 beats per
minute. Use the range rule of thumb to identify the limits
separating values that are significantly low or significantly high.
Is a pulse rate of 56.4 beats per minute significantly low or
significantly high?

The lengths of adult males' hands are normally distributed with
mean 186 mm and standard deviation is 7.3 mm. Suppose that 10
individuals are randomly chosen. Round all answers to 4 where
possible.
For the group of 10, find the probability that the average hand
length is less than 187.
Find the first quartile for the average adult male hand length
for this sample size.

The lengths of adult males' hands are normally distributed with
mean 190 mm and standard deviation is 7 mm. Suppose that 48
individuals are randomly chosen. Round all answers to 4 where
possible.
For the group of 48, find the probability that the average hand
length is less than 192.
Find the third quartile for the average adult male hand length
for this sample size.
For part b), is the assumption that the distribution is normal
necessary?
