<h3>Answer: Choice A) 8</h3>

===========================================================

Explanation:

3D figures can be tricky to visualize when looking at a 2D flat surface.

One way to picture this is to imagine a house. The first floor is what I've highlighted in figure 1 (see attached image below). The second floor is in figure 1, and the third floor is in figure 3.

We have 5 blocks on the first floor, 2 blocks on the second floor, and 1 block on the third floor. This is a total of 5+2+1 = 8 blocks.

What is y+6=5x please show steps to solve
NemiM [27]
We can solve for x or solve for y,
for x
y+6=5x
divide both sides by 5
\frac{y+6}{5}=x

for  y
y+6=5x
minus 6 from both sides
y=5x-6

D) Suppose you pick one marble from the bag at random. Find the expected value of its number.
Vaselesa [24]

C) The probability that you pick at least one purple marble is 98%.

<h3><u>Probability</u></h3>

The question is incomplete, since the number of marbles of each color in the bag is missing: 3 blue, 5 green, and 2 purple marbles.

Now, to answer the questions, the following calculations must be done:

  • C) 100 - (2/9x9) = X
  • 100 - 2 = X
  • 98 = X

Which of the following approaches cannot be used to perform a two-tailed hypothesis test about μ?
Burka [1]

Answer:

Option a)  Compare the level of significance to the confidence coefficient.

Step-by-step explanation:

We are given the following information in the question:

We are performing a two-tailed test hypothesis. We can follow the following approaches:

Option a)  Compare the level of significance to the confidence coefficient.

This cannot be used to perform hypothesis.

Option b) Compare the value of the test statistic to the critical value.

If the test statistic lies in the acceptance region evaluated by the critical value, we accept the null hypothesis. If not, we reject the null hypothesis.

Option c) Compare the confidence interval estimate of μ to the hypothesized value of μ.

If the estimated population lies in the calculated confidence interval, we accept the null hypothesis otherwise, we reject the null hypothesis.

Option d) Compare the p-value to the value of α.

If the p-value is greater than the significance level, we accept the null hypothesis. If it is lower than the significance level, we reject the null hypothesis.
