Several years ago, the mean height of women 20 years of age or older was 63.7 inches. Suppose that a random sample of 45 women w
VikaD [51]

Since the p - value is less than significance level . So, we will accept the null hypothesis.

​(a) State the appropriate null and alternative hypotheses to assess whether women are taller today.

Definition of null hypothesis : The null hypothesis attempts to show that no variation exists between variables or that a single variable is no different than its mean. it is denoted

Alternative Hypothesis : In statistical hypothesis testing, the alternative hypothesis is a position that states something is happening, a new theory is true instead of an old one (null hypothesis).

We are given that The mean height of women 20 years of age or older was 63.7 inches.

So, null hypothesis :  H₀ : μ = 63.7

Alternative Hypothesis :  H₁ : μ > 63.7

b)The​ P-value for this test is 0.06.

The p-value represents the probability of getting a sample mean height of 20 years old women is  64.1 inches.

c) Write a conclusion for this hypothesis test assuming an alpha equals 0.10 level of significance.

p- value = 0.06

Since the p - value is less .

So, we will accept the null hypothesis

So,  

Hence The mean height is 63.7 inches

Which of the binomials below is a factor of this trinomial? -3x^2-21x+24 x-4 x+1 x+4 x-1
OleMash [197]

Answer:

-3x^2-21x+24

Step-by-step explanation:

Kindly separate the answer choices:  (x - 4), (x + 1), (x + 4) , (x - 1).  The trinomial is thus -3x^2-21x+24, which can be factored as follows:  -3(x^2 + 7x - 8)

Then we have -3x^2-21x+24 = -3(x^2 + 7x - 8), which factors further into:

-3(x + 8)(x -1)  and so we conclude that the only binomial that is a factor of

-3x^2-21x+24 is (x - 1).
