For a population with m = 60, which of the following values for the population standard deviation would cause X = 68 to have the

Answer:

Option D) s = 1

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 69

X = 68

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

Computing z-scores for different standard deviation:

$z_1 = \displaystyle\frac{68-60}{4} = 2\\\\z_2 = \displaystyle\frac{68-60}{3} = 2.667\\\\z_3= \displaystyle\frac{68-60}{2} = 4\\\\z_4 = \displaystyle\frac{68-60}{1} = 8$

The standard deviation with highest z-score gives the most extreme position in the distribution.

Thus, the most extreme position of X = 68 in the distribution is given by a standard deviation of 1.

Mary leaves London at 12:00 and expected to arrive in Dorset at 13:00, however she had to detour due to road works eventually ar

Andreyy89

So she started at 12 and ended at 14
14-12=2

she traveled for 2 hours

50miles per hour or 50m/h
(m=miles not minutes)
2 hours so
2h times 50m/h
100miles traveled
