Answer to Problem 17E
No, there is insufficient evidence to reject the Mendel’s belief
Explanation of Solution
Given:
There are 3 peas for every 1 wrinkled pea.
Formula used:
The formula to compute the test statistic is
Calculation:
The proportions are:
The null and alternative hypotheses are:
The calculation for test statistic is done as:
Observed value | ||||
423 | 417 | 6 | 36 | 0.0863 |
133 | 139 | -6 | 36 | 0.259 |
The test statistic is:
The degree of freedom is calculated as:
The p-value using chi-square table at 1 degree of freedom is 0.3453.
The p -value is above significance level. The null hypothesis does not get rejected. Thus, there is not sufficient evidence to refute the claim of Mendel’s belief
