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

Answer:

<em>$40 </em>will be the total cost of the ribbon.

Step-by-step explanation:

To find the cost of ribbon to be put on the edges of rectangular banner, we need to:

1. Find the perimeter of the rectangle.

2. Multiply the perimeter with the per foot cost to find the total cost.

Let us find the perimeter first:

Perimeter of a rectangle is given as:

$P = 2 \times \text{(length+width)}$

Here, the dimensions of rectangle are 4ft by 6ft.

So, perimeter = $2 \times (4+6) \Rightarrow 20\ ft$

It is given that per foot cost is $2.

Total cost of the ribbon = $2 \times 20 \Rightarrow $40$

<em>$40 </em>will be the total cost of the ribbon.

If you divided 20acres of land into 1\4 acre section how !any sections doses it divied to

LuckyWell [14K]

If you divide 20 acres into 1/4 sections you'll get
20 ÷ 1/4 sections. When you divide fractions, you just multiply the reciprocal.

20 ÷ 1/4 =
20 × 4/1 = 80 sections
