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

Find m<2<br> See picture for full problem. Please and thank you!

aev [14]

Step-by-step explanation:

as the other triangle is Isosceles triangle which means it's two sides are equal and two angles are equal so

to find its 3rd angle apply angles sum property on it

according to which

2(68) + x = 180

136 + x = 180

x = 180 - 136

x = 44°

also we know, the other triangle is right angled triangle

so, it's one angle is 90° and 2nd angle is 44° (Vertically opposite angle)

therefore to know measure of angle 2 apply angle sum property of triangle in it too.

so,

90 + 44 + angle 2 = 180

134 + angle 2 = 180

angle 2 = 180 - 134

angle 2 = 46°

therefore, angle 2 is 46°

hope this answer helps you dear!

Suppose you roll a standard number cube and spin a spinner with four equal-sized sections labeled 1, 2, 3, 4. What is the probab

Kitty [74]

Answer:

25% probability you will roll a prime number and spin a prime number

Step-by-step explanation:

If we have two events, A and B, and they are independent, we have that:

$P(A \cap B) = P(A) \times P(B)$

In this question:

Event A: Rolling a prime number.

Event B: Spinning a prime number.

Both the cube and the spinner have four values, ranging from one to four.

2 and 3 are prime values, that is, 2 of those values. Then

$P(A) = P(B) = \frac{2}{4} = \frac{1}{2}$

What is the probability you will roll a prime number and spin a prime number

The cube and the spinner are independent of each other. So

$P(A \cap B) = \frac{1}{2} \times \frac{1}{2} = \frac{1}{4} = 0.25$

25% probability you will roll a prime number and spin a prime number
