Mathematics: The U.S. Federal Seed Act establishes germination rates for various fruit and vegetable seeds. Watermelon seeds are to meet a 70% germination standard. A skeptical gardener who has not had very good luck planting watermelons believes that the seed company he purchases seeds from is not adhering to the 70% federal mandate. Once a week for 12 weeks, he purchases a pack of 10 watermelon seeds to act as his sample. He plants the seeds in a greenhouse with good soil to maintain a consistent temperature

Following are the responses to the given question:

Step-by-step explanation:

Level of Significance, $\alpha = 0.05$

Sample Size, n = 120

Sample Proportion, $\hat{P} = 0.600$

$z -value = Z_{\frac{\alpha}{2}} = 1.960 \ \ [excel formula =NORMSINV(\frac{\alpha}{2})]$

Standard Error $SE = \sqrt{\frac{\hat{p}(1-\hat{p})}{n}} = 0.0447$

margin of error $E = Z\times SE = 1.960 \times 0.0447 = 0.0877$

When $95\%$ Confidence Interval

Interval Lower Limit $= \hat{p} - E = 0.600 - 0.0877 = 0.5123$

Interval Upper Limit $=\hat{p}+ E = 0.600 + 0.0877 = 0.6877$

the monthly payment is $636.02

Step-by-step explanation:

The computation of the monthly amount deposited i.e. PMT is given below:

GIven that

NPER = 15 × 12 months = 180

RATE = 5% ÷ 12 = 0.4167%

PV = $0

FV = $170,000

based on the above information

The formula is shown below:

= PMT(RATE;NPER;PV;FV;TYPE)

AFter applying the above formula, the monthly payment is $636.02
