Answer:

The probability that the sample proportion will be at least 3 percent more than the population proportion is 0.6157

Step-by-step explanation:

We need sample proportion between 0.75 - 0.03 = 0.72 and 0.75 +0.03 = 0.78. Here we have p = 0.75 and n= 158.

So z-score for sample proportion q = 0.72

z = $\frac{q - p}{\sqrt{\frac{p(1-p)}{n} } }$ = $\frac{0.72 - 0.75}{\sqrt{\frac{0.75(1-0.75)}{158} } }$ = - $\frac{0.03}{0.0344}$ = - 0.872

So z-score for sample proportion q = 0.78

z= $\frac{q - p}{\sqrt{\frac{p(1-p)}{n} } }$ = $\frac{0.78 - 0.75}{\sqrt{\frac{0.75(1-0.75)}{158} } }$ = $\frac{0.03}{0.0344}$ = 0.872

Therefore the probability that the sample proportion will be within 3 percent of the population proportion is

P( 0.72 < q < 0.78) = P ( -0.872 < z < 0.872)

= P( z < 0.872) - P( z < -0.872)

= 0.80785 - 0.19215

= 0.6157

If f(x) is the height, in cm, of a sunflower plant that is x days old, which of the following statements best describes the mean

mario62 [17]

Answer:

Step-by-step explanation:

We are given f(x) is height in cm while x is days old.

We are also given f(60)=210.

If you compare f(60) to f(x) you should see that x is 60 so we have the sunflower is 60 days old. Since f(60)=210, then you have the height of the sunflower is 210 cm tall.
