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.

Assume that we use a perpetual inventory system and that five identical units are purchased at the following four dates and cost

quester [9]

The cost of ending inventory at the conclusion of an accounting period is calculated using the weighted average inventory costing method.

<h3>How is the cost of discontinuing inventory calculated?</h3>

The cost of ending inventory at the conclusion of an accounting period is calculated using the weighted average inventory costing method. The idea behind this approach is to give all inventory units an average cost.
In this scenario, the average of the purchase costs from April 5 to April 22 would be taken and multiplied by the number of remaining units to get the cost of the ending inventory on the balance sheet.
The five pieces cost a total of $69 ($10 + $12 + $14 + $16 + $17) between April 5 and April 22. The remaining four units would make up the ending inventory as one unit was sold on April 25.
Therefore, $17.25 ($69 divided by 4) would be the price of the closing inventory. As the cost of the ending inventory, this sum would be shown on the balance sheet.
