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:

Step-by-step explanation:

Tricky. Very neat.

You are missing the minor arcAC and you need it, but don't fret. It can be found.

The formula for this is x = 1/2(Major Arc(235) - Minor Arc(see below) )

The minor arc is the supplement of x.

The minor arc is also equal to the the central angle

So the minor arc is 180 - x

x = 1/2 (235 - (180 - x) )                    Remove the inside  brackets

x = 1/2 (55  + x )                               Remove the remaining brackets

x = 1/2 *55 + 1/2x                             Subtract 1/2x from both sides

1/2 x = 27.5                                      Multiply both sides by 2

x = 55
