A streaming music site changed its format to focus on previously unreleased music from rising artists. the site manager now want

s to determine whether the number of unique listeners per day has changed. before the change in format, the site averaged 131,520 unique listeners per day. now, beginning three months after the format change, the site manager takes a random sample of 30 days and finds that the site now has an average of 124,247 unique listeners per day. the manager finds that the p-value for the hypothesis test is approximately 0.0743. what can be concluded at the 95% confidence level?

Answer : The p-value of 0.0743 is greater than alpha at 0.05; so we fail to reject the null hypothesis and conclude that there is no significant difference in the number of unique users before and after a change in policy.

In this question, the manager wants to know if the number of users has changed.

So, the null and alternate hypotheses are:

Null Hypothesis: {H_{0}}: \mu = 131,520

Alternate Hypothesis : {H_{1}}: \mu \not\equiv 131,520

Type of test : Two-tailed test

The level of significance is 95%

We can calculate alpha (α) as follows:

\alpha = 1- Confidence Level

\alpha = 1- 0.95
\alpha = 0.05

The p value = 0.0743.

We use the following rules to arrive at a conclusion when p-values and alpha is given:

If p-value < \alpha, reject the null hypothesis

If p-value \geq \alpha, we don't reject the null hypothesis.

Since the p-value is greater than alpha, we don't reject the null hypothesis.

Lesechka [4]

The answer is<u> "proof-of-concept prototype".</u>


A proof of concept is a framework structured simply to exhibit the usefulness of a solitary or little arrangement of standards to be coordinated into different frameworks. True ease of use isn't viewed as while making a proof of idea since incorporation with other faulty advancements isn't just tedious, however may weaken the capacity to decide whether the standard idea is practical.  

A prototype is a first endeavor at making something that may be true usable. It is assumed that you may misunderstand things all the while, yet finding that out is the standard motivation behind a model. A model will have all (or almost all) of the usefulness of the completed item, however will for the most part not be as proficient, tastefully satisfying, or strong.

Dennis_Churaev [7]

Answer:

a.  450 tours per month

b.  $850 per month

c.  CM Ratio = 0.7

d.  

1.  Increase

2.  Decrease

3.  No Effect

Explanation:

<u>The questions are:</u>

<u>a. Compute the average number of tours the company must conduct per month to break even</u>

<u>b. Compute the average sales revenue needed per month to produce a target average profit of $53,200</u>

<u>c. Calculate the contribution margin ratio. (Round your answer to 2 decimal places.)</u>

<u>d. Determine whether the actions that follow will increase, decrease, or not affect the company's break-even point. </u>

<em>1. A decrease in tour prices.</em>

<em>2. The termination of a salaried clerk (no replacement is planned).</em>

<em>3. A decrease in the number of tours sold.</em>

<u />

<u />

<u>Solution:</u>

a.

Selling Price = 190

VC = 57

Unit Contribution Margin = $133

Fixed Cost = 718,200 yearly, so monthly is:

718,200/12 = 59,850

Break even occurs when by selling tours they will cover monthly fixed cost of 59,850 [each tour will get 133], thus:

59,850/133 =  <u>450 tours per month</u>

<u></u>

b.

718,200 FC yearly, means, monthly:

718,200/12 = $59,850

Profit needed 53,200, so we would need to cover:

53200+59850 = $113,050

Each tour gives Unit CM to be $133, so we would need revenue of:

Rev = 113,050/133 = <u>$850</u>

<u></u>

c.

Contribution margin ratio is the quotient of difference in sales and var expenses to sales.

So,

CM Ratio = (Sales - Var Exp) / Sales

CM Ratio = (190 - 57) / 190 = 0.7

d.

1.

If the tour prices, decrease, there will be less revenue coming in so the break even point would go higher.

So, break even point will increase

2.

If a salaried clerk is terminated, it will decrease the salary costs of the company. This is decrease the fixed costs of the company (annual wages and salaries), thus it will be easier to cover the new, lower, fixed costs. Thus, the break even point will decrease

3.

A decrease in number of tours sold would proportionally change the variables and other costs and revenues associated. If you look at the calculation above, you will see that "number of tours" won't affect the Break Even Point. Thus, this action will create "no effect".
