Music streaming services are the most popular way to listen to music. Data gathered over the last 12 months show Apple Music was used by an average of 1.73 million households with a sample standard deviation of 0.46 million family units. Over the same 12 months Spotify was used by an average of 2.17 million families with a sample standard deviation of 0.33 million. Assume the population standard deviations are not the same. Using a significance level of 0.01, test the hypothesis of no difference in the mean number of households picking either service.
Answers
Answer:
There is enough statistical evidence to suggest that there is no difference between the mean number of households picking either service
Step-by-step explanation:
The parameters of the music streaming service are;
The average number of households using Apple Music, [tex]\overline {X}_1[/tex] = 1.73 million
The standard deviation, σ₁² = 0.46 million
The average number of households using Spotify, [tex]\overline {X}_2[/tex] = 2.17 million
The standard deviation, σ₂² = 0.33 million
The significance level = 0.01
Hypothesis testing with different population standard deviation
[tex]Z = \dfrac{\overline {X}_1 - \overline {X}_2}{\sqrt{\dfrac{\sigma_1^2}{n_1} +\dfrac{\sigma_2^2}{n_2}} }[/tex]
H₀: [tex]\overline {X}_1[/tex] ≠ [tex]\overline {X}_2[/tex]
H₁: [tex]\overline {X}_1[/tex] = [tex]\overline {X}_2[/tex]
[tex]Z = \dfrac{1.73- 2.17}{\sqrt{\dfrac{0.46^2}{12} +\dfrac{0.33^2}{12}} } = -2.6923[/tex]
p-value for the test statistic = 2 × P(Z <-2.6923) = 2 × 0.00357 = 0.00714
Therefore, the p-value is less than the significance level, and it is therefore unlikely that the result will be observed under the null hypothesis
We therefore reject the null hypothesis and there is enough statistical evidence to suggest that there is no difference between the mean number of households picking either service

Is s=2/3 a solution of 6s−1=3s?
Answers
Answer:
nope
Step-by-step explanation:
No, s=2/3 is not a solution of 6s−1 = 3s.
What is linear equation?Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.
Given:
A linear equation,
6s − 1 = 3s.
Substituting,
s = 2/3,
Equation is,
3 ≠ 2
Simplifying,
6s - 3s = 1
3s = 1
s = 1/3
That means, s = 1/3 is the only solution of the equation.
Therefore, s = 2/3 is not a solution to the equation.

At noon, a barista notices that she has $30 in her tip jar. If she makes an average of $0.45
from each customer, how much will she have in her tip jar if she serves n customers during
her shift?
(equation)
How much will she make if she serves 134 customers?
How many customers did she serve by noon?
Answers
Answer:
a [tex]A = 30 + 0.45 n[/tex]
b [tex]A = 90.3[/tex]
c 0 customers
Step-by-step explanation:
Given
[tex]Base\ Amount = 30[/tex]
[tex]Rate = 0.45[/tex] per customer
Solving (a): Amount (A) on n customers
This is calculated as:
[tex]A = Base\ Amount + Rate * n[/tex]
[tex]A = 30 + 0.45 * n[/tex]
[tex]A = 30 + 0.45 n[/tex]
Solving (b): Amount on 134 customers
In this case: n = 134
So:
[tex]A = 30 + 0.45 * 134[/tex]
[tex]A = 30 + 60.3[/tex]
[tex]A = 90.3[/tex]
Solving (c): Customers at noon.
At noon, the amount is 30.
So:
[tex]A = 30 + 0.45 n[/tex]
[tex]30 = 30 + 0.45n[/tex]
Collect like terms
[tex]0.45n = 30 - 30[/tex]
[tex]0.45n =0[/tex]
[tex]n = 0[/tex]

O Perimeter - 126 cm, area = 131.25 cm?
O Perimeter = 46 cm, area = 972 cm?
Perimeter = 126 cm, area = 972 cm2
Perimeter - 46 cm, area = 131.25 cm2
Answers
Answer:
Perimeter is 126cm and area is 972[tex]cm^2[/tex]
Step-by-step explanation:
Scale factor means you multiply the dimensions by the factor. In this case 4.5
The width 6cm becomes 27cm. The length 8cm becomes 36cm.
Perimeter = 2*L + 2*W, L is length and W is width.
[tex]P=27*2cm+36*2cm\\P=54cm+72cm\\P=126cm[/tex]
Area = L*W
[tex]A=27cm*36cm\\A=972cm^2[/tex]
