Answer:
66
Step-by-step explanation:
(5 - 3)⁴ - 2(7) + 8²
PEMDAS
Parentheses first
(2)⁴ - 2(7) + 8²
Exponents
16 - 2(7) + 64
Multiply and divide from left to right
16 -14 +64
Add and subtract from left to right
2+64
66

Answer:
It mean that the observed progeny is similar than the expected progeny. There is no a relationship between the categorical variables.
Step-by-step explanation:
The Chi-squared test is used to test the relationship between categorical variables. A categorical variable is a non-numerical variable. The null hypothesis of the Chi-squared test is that categorical variables are independent; it means that the frequencies are not dependent on the variable. It is important to know that the Chi-squared test does not measure causality, it only measures the relationship. To reject the null hypothesis, you usually need a probability lower than 0.05, but in this case, the probability was way higher than 0.05, it was between 0.5 and 0.9.
