Departmental Store Agora claims that their mean weekly sales of Aerosol were at most 2,400 packages over the past 6 months and population distribution is unknown. The manager wants to check if the sales have decreased in recent times. He obtained a random obtained sample of sales data from 61 stores and found that the sample mean is 3,593 packages with sample standard deviation 4919. At 7% significance level, using critical value approach see if the claim is true or not.
Answers
Answer:
There is enough statistical evidence to suggest that the department's claim is not true
Step-by-step explanation:
The mean weekly sales μ₀ ≤ 2,400 packages
The period over which the weekly sales were measured = Over the last 6 months
The number of stores in the sample, n = 61 stores
The sample mean, [tex]\overline x[/tex] = 3,593
The sample standard deviation, s = 4919
The significance level = 7% = 0.07
The critical value approach
The null hypothesis, H₀; μ ≤ μ₀
The alternative hypothesis, Hₐ; μ > μ₀
The test statistic is given as follows;
[tex]t=\dfrac{\bar{x}-\mu }{\dfrac{s}{\sqrt{n}}}[/tex]
We get;
[tex]t=\dfrac{3,593-2,400}{\dfrac{4,919}{\sqrt{61}}} \approx 1.894[/tex]
With df = n - 1 = 61 - 1 = 60 at 7% significant level, from a graphing calculator the critical-t, = 1.495598
The p-value at the test statistic is between 0.01 and 0.005
Given that the p-value is less than the significant level, and the test statistic is larger than the critical-t we reject the null hypothesis, that the mean weekly aerosol sale is less than 2,400 packages.
Therefore, there is sufficient statistical evidence to suggest that the departments claim is not true and the mean sales of Aerosols have increased to more than 2,400 packages
Carla is a waitress at Daybreak Diner and she earns $5 for each hour she works. Last week she earned 148 total including $68 tips how many hours did Carla work last week
Answers
Answer: 16 hours
Step-by-step explanation:
Given
Carla earns [tex]\$5[/tex] for each hour she works
Last week she earned $148 total including [tex]\$68[/tex] tip
So, the sum of hourly income and must be equal to the total money earned
Suppose she works for [tex]x[/tex] hours

Answer:
Average daily balance ≈ $873
Step-by-step explanation:
We are told the balance were;
$1,000 for 9 days
$750 for 10 days
$850 for 4 days
$900 for 7 days
Thus;
Average = ΣFx/Σx
Where ΣFx = (1000 × 9) + (750 × 10) + (850 × 4) + (900 × 7)
ΣFx = $26,200
Σx = 9 + 10 + 4 + 7
Σx = 30
Thus;
Average daily balance = 26200/30
Average daily balance ≈ $873

Find the area of the following rectangle. Type out al work

Step-by-step explanation:
[tex]area = length \times width \\ = (4x + 3) \times (2x + 2) \\ = ( {8x}^{2} + 8x + 6x + 6) \\ = ( {8x}^{2} + 14x + 6) \: {units}^{2} [/tex]
Answer:
[tex](8x + 14x + 6)^{2}[/tex]
Step-by-step explanation:
Area of a rectangle is length x breadth
In the given figure, the length is 2x + 2 and breadth is 4x + 3
So, the area would be:-
(2x + 2) (4x + 3)
[tex]8x^{2}[/tex] + 6x + 8x + 6
So the area would be => [tex](8x + 14x + 6)^{2}[/tex]
Un comerciante tiene 1108 cajas de zapatos y los quiere guardar en el cajon de su camion. Para saber si caben todas las cajas el coloca 20 a lo largo,7 a lo ancho y 8 a lo alto ¿puede guardar todas las cajas de zapatos en el cajon?
Answers
Answer:
El comerciante NO PUEDE guardar todas las cajas de zapatos en el cajón
Step-by-step explanation:
Tenemos que encontrar el volumen de la caja.
Se nos dice en la pregunta que:
Coloca 20 a lo largo, 7 a lo ancho y 8 a la altura.
Volumen = Largo × Ancho × Alto
Largo = 20, Ancho = 7, Alto = 8
Volumen = 20 × 7 × 8
= 1120
También se nos dice que: el comerciante tiene 1108 cajas de zapatos y quiere guardarlas en el cajón de su camión.
Comparando esto con nuestro cálculo anterior, el comerciante NO PUEDE guardar todas las cajas de zapatos en el cajón

if the HCF of 408 and 1032 is expressible in the form of 1032 into 2 + 408 into P then find the value of p
Answers
Answer:
below.
Step-by-step explanation:
408 = 2*2*2*3*17
1032 = 2*2*2*3*43
So the HCF is 2*2*2*3 = 24
24 = 2/1032 + p/408
24 - 2/1032 = p/408
p = (24 - 2/1032) * 408
p = 9791.21 to nearest hundredth.
Ms. Garcia burns 236 calories riding her bike each
hour. She wants to burn more than 354 calories
riding her bike at the same rate.
Which inequality represents all possible values for
t, the number of hours Ms. Garcia must ride her
bike to burn more than 354 calories?
A t < 1.5
B t > 1.5
C t < 0.5
D t > 0.5
Answers
The inequality that represents all possible values for t is:
t > 1.5
Which inequality is the correct one?
We know that she burns 236 calories per hour, so if she rides for t hours, she burns a total of:
t*236 calories.
Now, she wants to burn more than 354, so we have the inequality:
t*237 > 354
Solving for t (by dividing both sides by 237) we get:
t > 354/237 = 1.5
t > 1.5
So the correct option is B.

Answers
Answer:
55 degrees
Step-by-step explanation:
Angle ACE and BDE are congruent so segments AC and BD are parallel. That makes angles CAE and DBE congruent.
6x - 15 = 5x - 1
x - 15 = -1
x = 14
So, the measure of angle BDE = 4x = 56 degrees. The measure of angle DBE = 5x - 1 = 69 degrees.
The total of all angles in triangle BDE is 180 degrees, so the measure of angle E = 180 - 56 - 69 = 55
