H1: The Y category and X category are independent.Chi-square=f0-fe2fe X1 X2 X3 Total Y1 0.3247 0.0039 0.3076 0.6362 Y2 0.7362 0.0090 0.6975 1.4427 Total 1.0609 0.0129 1.0051 2.0789 So. the value for chi-square test is 2.0789. Now, degrees of freedom; df = (2-1)×(3-1)=2 P-value: Consider the level of significance be 0.05. χ(2.0789, 2)=0.354 The result is not significant at p<0.05 Fail to reject the null hypothesis. There is not sufficient evidence to conclude that two variables are independent.

The table contains observed values and expected values (in parentheses) for two categorical variables, X and Y, where variable X has three categories, and variable Y has two categories. Use the table to complete parts (a) and (b) below.

Categories:

- Variable X:
- $ X_1, X_2, X_3 $

- Variable Y:
- $ Y_1, Y_2 $

Observed and Expected Values:

\[
\begin{array}{c|c|c|c}
& X_1 & X_2 & X_3 \\
\hline
Y_1 & 32\ (35.39) & 44\ (44.42) & 51\ (47.19) \\
Y_2 & 19\ (15.61) & 20\ (19.58) & 17\ (20.81) \\
\end{array}
\]

Hypotheses:

- Option B:
- $ H_0 $: The Y category and X category have equal proportions.
- $ H_1 $: The proportions are not equal.

- Option C:
- $ H_0 $: The Y category and X category are dependent.
- $ H_1 $: The Y category and X category are independent.

- Option D:
- $ H_0 $: $\mu_x = E_x$ and $\mu_y = E_y$
- $ H_1 $: $\mu_x \neq E_x$ or $\mu_y \neq E_y$

Bill Alther is a zoologist who studies Anna's hummingbird (Calypte anna). (Reference: Hummingbirds, K. Long, W. Alther.)

The weights (in grams) were as follows. 3.7 2.9 3.8 4.2 4.8 3.1 The sample mean is = 3.75 grams. Let x be a random variable representing weights of hummingbirds in this part of the Grand Canyon. We assume that x has a normal distribution and σ = 0.64 gram. Suppose it is known that for the population of all Anna's hummingbirds, the mean weight is μ = 4.30 grams. Do the data indicate that the mean weight of these birds in this part of the Grand Canyon is less than 4.30 grams? Use ? = 0.10. (a) What is the level of significance? (Enter a number.)
