Fail to reject the null hypothesis.

Step-by-step explanation:

People who live in Florida and also have annual pass to Disney world is 221, sample size selected for group 1 is 350.

People who do not live in Florida and have annual pass to Disney world is 365, sample size selected for Group 2 is 650.

Group 1 sample proportion is : 221 / 350 = 0.6314

Group 2 sample proportion is 365 / 650 = 0.5615

Test statistics is 0.8317

Since test stats value is greater than the sample proportion significance level, we fail to reject the null hypothesis.

x - 2

Step-by-step explanation:

Given

$\frac{(x-1)(x-2)(x^2-9x+14)}{(x-7)(x^2-3x+2)}$

Factor the quadratics on the numerator and denominator

x² - 9x + 14 = (x - 7)(x - 2)

x² - 3x + 2 = (x - 1)(x - 2)

The expression can now be rewritten as

$\frac{(x-1)x-2)(x-7)(x-2)}{(x-7)(x-1)(x-2)\\}$

Cancel the common factors (x - 1), ( x - 2) and (x - 7) on numerator/ denominator, leaving

x - 2 ← in simplest form
