Answer:

(A) There is convincing evidence that there is no difference in the mean delivery times.

(B) There is convincing evidence that there is a difference in the mean delivery times.

(C) There is convincing evidence that the mean delivery time from Japan to Texas is greater than the mean delivery time from Texas to Japan.

(D) There is not convincing evidence that the mean delivery time from Japan to Texas is greater than the mean delivery time from Texas to Japan.

(E) The t-test cannot be used for sample sizes that are this small.

Explanation:

The correct option is;

(A) There is convincing evidence that there is no difference in the mean delivery times.

Step-by-step explanation:

Here we have the formula for the two-sample t-test given s;

To Texas N₁ = 12, =8.74 σ₁ = 2.92 SE Mean₁ = 0.84

To Japan N₂ = 9 = 6.75 σ₂ = 2.56 SE Mean₁ = 0.85

t = 1.667

Where the null hypothesis is

mu To Texas = mu To Japan and the alternative is

mu To Texas > mu To Japan

Here since the observed P value of P = 0.058 is greater than the significance level of 0.05 we fail to reject the null hypothesis and we will therefore, not accept the alternative hypothesis.

Hence, there is convincing evidence that there is no difference in the mean delivery times.

Sliva [168]

When you have to write about what you do in your spare time, you need to write about your hobbies.

ikadub [295]

The given statement is False. Baker, Schultz, and Halstead argue that the United States can reap significant strategic and economic benefits by investing in cleaner energy technologies and supporting international efforts to reduce carbon emissions.

Carbon emissions are the primary cause of global climate change. It is widely acknowledged that in order to avoid the worst effects of climate change, the world must urgently reduce emissions. However, how this responsibility is distributed among regions, countries, and individuals has long been a source of contention in international discussions.

This debate stems from the various ways emissions are compared, including annual emissions by country, emissions per person, historical contributions, and whether or not they account for traded goods and services. These metrics can tell a variety of stories.

~A certain rectangular prism has a height of h inches, a width that is 3 inches less than its height, and a length that is 4 inc

3241004551 [841]

Answer:

Volume = 480 cubic inches

Explanation:

We have the following relationships to work with

width w = h -3

length l = h + 4

area of base of prism a = l x w = 60 (1)

area of base in terms of h = (h-3)(h+4) =h² -3h + 4h -12 (2)

Setting (1) = (2) gives

h² + h -12 =60

h² + h -72 = 0

Factoring the LHS we get

(h+9)(h-8) = 0

The solutions for h are

h + 9 = 0 ==> h = -9

h - 8 = 0 ==> h = 8

Since h cannot be negative, h = 8 inches

Volume = base area x h = 60 x 8 = 480 cubic inches

We do not have to calculate length and width separately, but if so,

w = 8 -3 = 5

l = 8 + 4 = 12
