mote1985 [20]

Answer:

Eve used scale as 2 yards is equal to 1 inch.

Step-by-step explanation:

Given:

Actual Picnic area = 68 yards.

Drawing Picnic area = 34 inches.

We need to find the scale used by Eve.

Solution:

Now we can say that;

scale used by Eve can be calculated by dividing Actual Picnic area from drawing picnic area.

framing in equation form we get;

scale used by Eve = \frac{68}{34} = 2\ yd/in

Hence Eve used scale as 2 yards is equal to 1 inch.

Answer:

26.5265

Step-by-step explanation:

<u>Confidence Interval</u>

When the population standard deviation \sigma is known, the formula for a confidence interval for a population mean \bar x is:

\displaystyle \bar x \pm z\frac{\sigma}{\sqrt{n}}

Where n is the sample size and z is the corresponding z-value from the standard normal distribution for the selected confidence level. The value of z for a 95% confidence interval is z=1.96. The rest of the values are

\bar x=28.2,\ \sigma=2.7, \ n=10

Calculating the confidence interval

\displaystyle 28.2 \pm 1.96\frac{2.7}{\sqrt{10}}

\displaystyle 28.2 \pm 1.6735

Or, equivalently

26.5265
