Answer from: oomale

The estimate for the percentage of yellow peas lie within the confidence interval 23.66% and 30.83 %

Since the expected value for the estimate of the yellow peas lies between the confidence interval it means that the given estimate of yellow peas does not contradict the expectation

Step-by-step explanation:

From the question we are told that

The number of green peas is g = 453

The number of yellow peas is y = 163

The sample size is n = y + g = 435 + 163 = 598

The sample proportion of the yellow peas is $\r p_y = \frac{y}{n}$

substituting values

$\r p_y = \frac{163}{598}$

$\r p_y = 0.2726$

Given that the confidence level is c = 95 %

The level of significance is $\alpha = 100 - 95 = 5$ %

The critical values at this level of significance is obtained from the table of critical values as

$t_{\alpha } = 1.960$

Now the confidence interval is mathematically evaluated as

$k = \r p _y \pm t_{\alpha } \sqrt{\frac{\r p (1 - \r p) }{n} }$

substituting values

$k =0.2726 \pm 1.96 \sqrt{\frac{0.2726 (1 - 0.2726) }{598} }$

$k =0.2726 \pm 0.036$

So the 95% confidence interval is

k = ( 0.2366, 0.3083)

This mean that the estimate of the yellow peas(25%) lies between

23.66% and 30.83 %

Given that the expected value for the estimate of the yellow peas lies between the confidence interval it means that the given estimate of yellow peas does not contradict the expectation

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
