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.
Answer:
2
Step-by-step explanation:
Multiply your monthly by 12
2543 x 12 = 30,516
There are 2 x’s so it’s 2x^2 + 9x because 2x4 is 8 + 1 x and then + 4 because you connect like terms so it would be 2x^2+9x+4
