The proportion of peas with yellow pods is equal to 0.25. Then the value of the test statistics of peas with yellow pods is 2.68.

What are statistics?

Statistics is the study of collection, analysis, interpretation, and presentation of data or to discipline to collect, summarise the data.

Given

The claim is that the proportion of peas with yellow pods is equal to 0.25 (or 25%).

The sample statistics from one experiment include 460 peas with 91 of them having yellow pods.

Sample size = 460

The proportion of peas with yellow pods in the sample.

$\rm P = \dfrac{91}{460} = 0.1978 \approx 0.2$

Now, the test statistic for the population proportion is given by;

$\rm z = \dfrac{p-P}{\sqrt{\frac{P(1-P)}{n}}}\\\\z = \dfrac{0.25-0.2}{\sqrt{\frac{0.2(1-0.2)}{460}}}\\\\z = 2.68$

Thus, the value of the test statistics is 2.68.

2.68

Step-by-step explanation:

Claim : The proportion of peas with yellow pods is equal to 0.25

i.e. p=0.25

Sample size : 460

Proportion of peas with yellow pods in sample :

$P=\dfrac{91}{460}=0.19782608695\approx0.20$

Now, the test statistic for the population proportion is given by :-

$z=\dfrac{p-P}{\sqrt{\dfrac{P(1-P)}{n}}}$

$\Rightarrow\ z=\dfrac{0.25-0.20}{\sqrt{\dfrac{0.20(1-0.20)}{460}}}\Rightarrow\ z=2.68095132369\approx2.68$

Hence, the value of the test statistic is 2.68
