Answer: 9a^4 - b^2

= (3a^2)^2 - b^2  

= (3a^2 + b)(3a^2 - b) using a^2 - b^2 = (a+b)(a-b)

The side length of aDavid is a statistician. He has a sample size of 40 (which he cannot change). What element of his hypothesis
Sergeeva-Olga [200]

Answer: D) the significance level of the test

=======================================================

Explanation:

The significance level of the test, also known as "alpha", is the probability of making a type 1 error. A type 1 error is where you reject the null hypothesis but it was true all along.

The null hypothesis is where we test a certain probability distribution (eg: normal distribution). Specifically we gather a sample of values and compute the test statistic. If the probability of getting that test statistic or more extreme is smaller than alpha, then we reject the null. This probability value is known as the p-value.

If you lower the alpha value, then that will make it more likely you do not reject the null. Consider an example where alpha = 0.10 to start with. If you get a p-value of 0.02, then you would reject the null. The same would apply for alpha = 0.05; however, with alpha = 0.01, the p-value is no longer smaller than alpha. At this point we do not reject the null. Your textbook may use the phrasing "fail to reject the null".

Going in the opposite direction, increasing the alpha value will make it more likely to reject the null. Each time you adjust the alpha value, keep the p-value to some fixed number (between 0 and 1).

Find the slope (m) and y -intercept (b) of the equation in standar form 2x-3y=6​
klasskru [66]

Answer:

m = \frac{2}{3} , b = - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

Given

2x - 3y = 6 ( subtract 2x from both sides )

- 3y = - 2x + 6 ( divide all terms by - 3 )

y = \frac{2}{3} x - 2 ← in slope- intercept form

with slope m = \frac{2}{3} and y- intercept b = - 2
