You are thinking about opening a restaurant and are searching for a good location. From research you have done, you know that th

e mean income of those living near the restaurant must be over $85,000 to support the type of upscale restaurant you wish to open. You decide to take a simple random sample of 50 people living near one potential location. Based on the mean income of this sample, you will decide whether to open a restaurant there. Describe a Type I and a Type II error, and explain the consequences of each

The type I error and type II error can be described as follows:

Type I error: We can conclude that if the mean exceeds $85000, when in fact it does not. Thus, opening your restaurant in a locale that will not support it).

Type II error: We can conclude that if the mean income does not exceed $85000, when in fact it does. Thus, deciding not to open your restaurant in a locale that will support it.

<h3>What is a Type I and a Type II error?</h3>

A Type I error in statistics is described as rejecting the null hypothesis when it is actually true, and a Type II error is defined as failing to reject the null hypothesis when it is genuinely untrue.

The type I error and type II error can be described as follows:

  • Type I error: We can conclude that if the mean exceeds $85000, when in fact it does not.
  • Type II error: We can conclude that if the mean income does not exceed $85000, when in fact it does.

The consequences of each error are:

If you launched your business in an inappropriate location, you would incur a financial loss before realizing your error.

If you do not open your restaurant in an ideal location, you will miss out on the potential to make a profit, but you will not necessarily lose money.

First, 9.8 (Gravity) times 3 (time) equals 29.4, which is the velocity after 3 seconds. The kinematic equation for change in position that uses the variables we have is:
delta x= (v)(t) -0.5(acceleration)(time)^2
delta x= 29.4 times (3) - 0.5 (9.8) times 9
delta x= 44.1
100 minus 44.1 equals 55.9, which is the answer for part a.

Tell me if you need any clarification

PART B:
The kinematic equation for this is:
delta x= (initial velocity) times time plus 0.5 (a)(time)^2
100=(0)times(x) plus 0.5 (a)(time)^2
100=0.5(9.8)(x)^2
100=4.9x^2
100/4.9 is approxamitely 20.4.
The squareroot of this is approxamitely 4.5.

A company’s sales decreased 5% this year to $6,585. What were their sales last year?
Feliz [49]

Answer:

$6932

Step-by-step explanation:

Let last year's sales = x.  Since there was a decrease of 5%, that means this year's sales are 95% of last year's sales.

So, .95x = 6585

x = 6932 to the nearest dollar
