A recent report in a women magazine stated that the average age for women to marry in the United States is now 25 years of age,

MrRissso [65]

Answer: 0.0136

Step-by-step explanation:

Given : Mean : $\mu=\ 25$

Standard deviation : $\sigma= 3.2$

Sample size : $n=50$

The formula to calculate the z-score :-

$z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

For x = 24

$z=\dfrac{24-25}{\dfrac{3.2}{\sqrt{50}}}=-2.20970869121\aprox-2.21$

The P-value = $P(z\leq24)=0.0135526\approx0.0136$

Hence, the probability that the sample mean age for 50 randomly selected women to marry is at most 24 years = 0.0136

Hi! hope this helped B(d) is a function of the number of days d since she opened the account.B(0) is the balance at day=0 now, since the length of segment OA is half of the length of segment OB, and the length of segment OB is proportional to the max balance, namely $400, then the segment OA is proportional to 400/2=200
