Answer:

Sample size should be atleast 617

Step-by-step explanation:

given that a 95% confidence interval for the mean of a population is to be constructed and must be accurate to within 0.3 unit.

i.e. margin of error <0.3

Std devition sample = 3.8

For 95% assuming sample size large we can use z critical value

Z critical = 1.96

we have

$1.96 * std error 616.3634$

Sample size should be atleast 617 to get an accurate margin of error 0.3

Answer:

352 ft²

Step-by-step explanation:

The formula for the area of a trapezoid is $A=(\frac{b_1+b_2}{2})h$ where $b_1$ and $b_2$ are the bases of the trapezoid and $h$ is the height, thus:

$A=(\frac{b_1+b_2}{2})h\\\\A=(\frac{13+31}{2})(16)\\\\A=(\frac{44}{2})(16)\\ \\A=(22)(16)\\\\A=352$

This means that the area of the trapezoid is 352 ft².
