Weird question. I would probably go with A because therapeutic music should calm someone down and make them feel better and good. Good luck!

I would have to go with A as well this is because it's like music therapy :)

In which grade do kids generally start to prepare for SAT exams?

harkovskaia [24]

We suggest starting to prep for the the SAT as early as eighth grade year. It sound early, but if a student plans on taking the SAT several times throughout high school, eighth graders can take a relaxed and long-view approach to prepping, and can plan on taking their first SAT sophomore year.

ehidna [41]

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.

A ceiling fan operates at three speeds, using 120 v of electricity from the wall. At low speeds, it uses 0. 25 a. Calculate the

wolverine [178]

A) The calculated resistance needed to generate the current at low speed is; R = 480 ohms

B) Resistance at medium and larger speeds are;

At medium speed; R is less than that at low speed

At larger speed; R is less than that at medium speed.

A) We are given;

Voltage; V = 120 V

Current at lower speed; I = 0.25 A

Formula for resistance here is;

R = V/I

R = 120/0.25

R = 480 ohms

B) This means that if larger currents are required at higher speeds, it means that lower resistance would be required.

Similarly at medium currents the resistance will be lesser than that at lower speed but greater than that at larger speeds.
