Answer:

This indicates that the chances of the mean life span today is greater than 70 years is 0.5871

Step-by-step explanation:

The past year showed an average life span of 71.8 years.

$\mu = 71.8 years$

Population standard deviation = 8.9 years

$\sigma = 8.9 years$

We are supposed to find the mean life span today is greater than 70 years

i.e. P(X>70)

Formula : $Z = \frac{x-\mu}{\sigma}$

$Z=\frac{70-71.8}{8.9}$

Z=−0.202

P(X<70)=0.4129

P(X>70)=1-P(X<70)=1-0.4129=0.5871

Hence This indicates that the chances of the mean life span today is greater than 70 years is 0.5871
