Question

The mean value of land and buildings per acre from a sample of farms is

$1800

with a standard deviation of

$200

The data set has a bell-shaped distribution. Assume the number of farms in the sample is

75

(a) Use the empirical rule to estimate the number of farms whose land and building values per acre are between

$1600

and

$2000

nothing

farms (Round to the nearest whole number as needed.)

Answer #1

Given,

= 1800, = 200

According to emperical (68 - 95 - 99.7) rule,

Approximately, 68% of the data falls between 1 standard deviation of the mean.

Approximately, 95% of the data falls between 2 standard deviation of the mean

Approximately, 99.7% of the data falls between 3 standard deviation of the mean

We have to calculate P(1600 < X < 2000) = ?

We write 1600 in terms of and as

1600 = 1800 - 200

1600 = - 1

That is 1600 is 1 standard deviation below the mean.

Similarly,

2000 = 1800 + 200

2000 = + 1

2000 is 1 standard deviation above the mean.

That is **1600 and 2000 are 1 standard deviation of the
mean.**

According to emperical rule,

**P(1600 < X < 2000) = 68%**
