Answer:

Step-by-step explanation:

This is an exponential function of the form F=Ir^t, in this case

t(x)=948(1-0.045)^x

t(x)=948(0.955^x)

So the first answer

The lengths of pregnancies in a small rural village are normally distributed with a mean of 264.1 days and a standard deviation
KiRa [710]

Answer:

The range of the 95% data (X) =  238.3 days <  X < 289.9 days

Step-by-step explanation:

Given;

mean of the normal distribution, m = 264.1 days

standard deviation, d = 12.9 days

between two standard deviation below and above the mean is 96% of all the data.

two standard deviation below the mean = m - 2d

                                                                   = 264.1 - 2(12.9)

                                                                   = 238.3 days

two standard deviation above the mean = m + 2d

                                                                    = 264.1 + 2(12.9)

                                                                     = 289.9 days

The middle of the 95% of most pregnancies would be found in the following range;

238.3 days <  X < 289.9 days

  • => 4.5m = 21.25 - 10
  • => 4.5m = 11.25
  • => m = 11.25/4.5
  • => m = 2.5

<u>Conclusion:</u>

Therefore, m = 2.5
