Answer 4:
The difference between the observed and the expected values for each category is 1.2
Answer 5:
?^2 = 1.2
Answer c:
Degrees of freedom, df = n - 1 = 6 - 1 = 5
Using chi-square tables, the probability is
P [X^2 (5) > 8.0843] = 0.1517
Answer c:
Degrees of freedom, df = n - 1 = 4 - 1 = 3
Using chi-square tables, the probability is
P [X^2 (3) > 3.4732] = 0.3243
Answer e:
Degrees of freedom, df = 2 - 1 = 1
Using chi-square tables, the p-value is
P [X^2 (1) > 656.51] = 0.000
Reject Ho
it should be something like this. please i need a detailed
explaintion on the answers to understand whats going

Given X, and x, distributions that are normal or approximately normal with unknown o, and on, the value of t corresponding to X, - X, has a distribution that is approximated by a Student's t distribution. We use the convention that the degrees of freedom is approximately the smaller of n - 1 and n, - 1. However, a more accurate estimate for the appropriate degrees of freedom is given by Satterthwaite's formula: 2 2 xn2 522 +$22) d.f. z...

In a flowering plant, red flowers are dominant over white flowers, and short plants are dominant over tall plants. A short plant with red flowers was self-fertilized and the phenotypes for the resulting progeny recorded (see below). Based on the observed numbers, you propose the hypothesis that this dihybrid cross follows a 9:3:3:1 phenotypic ratio, whereby Mendel's laws apply. Based on this hypothesis, you calculated the expected number of progeny for each phenotype (see below). Phenotype Observed Number of Plants...
