A farmer outside of Clinton NC plants 20 plots of a new type of corn. The average yield for these plots is ī= 150 bushels per ac
bogdanovich [222]

Answer:

The 95% confidence  interval is (150\pm 8.8).

Step-by-step explanation:

The information provided is:

\bar x=150\\\sigma = 20\\n=20

The critical value for 95% confidence level is:

z_{\alpha/2}=z_{0.05/2}=z_{0.025}=1.96

Compute the margin of error as follows:

MOE=z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}

          =1.96\times\frac{20}{\sqrt{20}}\\\\=1.96\times 4.47214\\\\=8.7653944\\\\\approx 8.8

Then the 95% confidence  interval is:

CI=\bar x\pm MOE

     =150\pm 8.8

Thus, the 95% confidence  interval is (150\pm 8.8).

Consider the following data set: <br> 11, 8, 0, 8, 13, 3, 14 <br> Find the median.
r-ruslan [8.4K]

Answer:

The median is 8.

How you get that is that you have to order these from smallest to biggest.

0,3,8,8,11,13,14

Next, you cut one from each side until you get one single number left. If you get two, then you add them together and divide it by 2.

Find the area of this triangle. Round to
DaniilM [7]

Answer:

63.3 square feet

Step-by-step explanation:

Let a = 20 ft, B = 15 ft, c = 9ft

s=\frac{a+b+c}{2}

s=\frac{20+15+9}{2}

s=\frac{44}{2}

s=22\: ft

Area \: of \:\triangle  =  \sqrt{s(s - a)(s - b)(s - c)}  \\  \\  = \sqrt{22(22 - 20)(22 - 15)(22 - 9)}  \\  \\= \sqrt{22 \times 2 \times 7 \times 13}  \\  \\= \sqrt{44 \times 91}  \\  \\ =  \sqrt{4,004}  \\  \\  = 63.2771681 \\  \\   \approx 63.3 \:  {ft}^{2}
