Use the following scenario for the next 4 questions: Based on the results of an annual customer satisfaction survey of State Farm policyholders, State Farm claims that policyholders have a customer satisfaction rate of greater than 90%. To check the accuracy of this claim, a random sample of 60 State Farm policyholders was asked to rate whether they were satisfied with the quality of customer service. Fifteen percent of these policyholders said they were not satisfied with the quality of service. Can we infer that the satisfaction rate is less than the claim with a level of significance of 5%
Answer:
Since the pvalue of 0.0985 > 0.05, we cannot infer that the satisfaction rate is less than the claim with a level of significance of 5%
Step-by-step explanation:
The null hypothesis is:
[tex]H_{0} = 0.9[/tex]
Because tate Farm claims that policyholders have a customer satisfaction rate of greater than 90%.
The alternate hypotesis is:
[tex]H_{1} < 0.9[/tex]
Because of the question: Can we infer that the satisfaction rate is less than the claim with a level of significance of 5%.
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
State Farm claims that policyholders have a customer satisfaction rate of greater than 90%.
This means that [tex]\mu = 0.9, \sigma = \sqrt{0.9*0.1}[/tex]
To check the accuracy of this claim, a random sample of 60 State Farm policyholders was asked to rate whether they were satisfied with the quality of customer service.
This means that [tex]n = 60[/tex]
Fifteen percent of these policyholders said they were not satisfied with the quality of service.
So 100 - 15 = 85% were satisfied, which means that [tex]p = 0.85[/tex]
Test statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{0.85 - 0.9}{\frac{\sqrt{0.9*0.1}}{\sqrt{60}}}[/tex]
[tex]z = -1.29[/tex]
[tex]z = -1.29[/tex] has a pvalue of 0.0985.
Since the pvalue of 0.0985 > 0.05, we cannot infer that the satisfaction rate is less than the claim with a level of significance of 5%

Bobby, Jessy, Carl, and Andrea are working a shift at the concession stand during their school football game. The football game has four quarters, and each person works one of the quarters.
Using the arrangements formula, it is found that there are 24 ways to arrange the people as such one works each quarter.
What is the arrangements formula?The number of possible arrangements of n elements is given by the factorial of n, that is:
[tex]A_n = n![/tex]
In this problem, 4 people will be arranged, hence:
[tex]A_4 = 4! = 24[/tex]
Hence, they can be arranged in 24 ways.

C. Find the equation that is parallel to y = 12x-2 and crosses the point (6,2)
Answer:
The equation of line a is y=(1/2)x−1, and it passes through point (6,2).
line b is: y = -2x + c and we use point (-6,2) to find b.
2 = -2(-6) + c
14 = c
The equation for line b is: y = -2x + 14
The y-intercept (which is the point where x=0) is the point (0,14.) So, y=14

Find the height of this cone using the Pythagorean Theorem. 9 in. h = [?] in. 6 in. a C Pythagorean Theorem: a2 + b2 = c2 b
Answer:
h = √72 in.
Step-by-step explanation:
Height of the cone using pythagorean theorem, a² + b² = c², where:
a = h
b = ½(6) = 3 in.
c = 9 in.
Plug in the values
h² + 3² = 9²
h² + 9 = 81
h² + 9 - 9 = 81 - 9
h² = 72
h = √72

20% of 30 ___30% of 40
Answer:
20% of 30 < 30% of 40
Step-by-step explanation:
Find 20% of 30
20/100 = x/30
Cross multiply
20 × 30 = 100 × x
600 = 100x
Divide both sides by 100
6 = x
Find 30% of 40
30/100 = x/40
Cross multiply
30 × 40 = 100 × x
1200 = 100x
Divide both sides by 100
12 = x
Compare the two answers:
6 and 12

Which line shows the first error in the solution?
Answer:
The first error is in line 1.
Step-by-step explanation:
The equation that represents the statement is:
[tex]4-\frac{x}{3}=11[/tex]
it is four (4) less than a number (x) divided by three (3) is 11.
Therefore, we need to start from this equation, so the first error is in line 1.

Plz help if correct ill give brailiest also the first answer was x<1
Answer:
For x<1, answer would be A.
Step-by-step explanation:
Since the less than sign doesn't have a line under it "making it less than or equal to" the dot on the graph is not shaded, and if you simply read the inequality, x is less than 1, so it goes in the direction less than 1.
