Step-by-step explanation:
The manager of a bakery states in a report that the average value of customer transactions is greater than $13.65. A random sample of 38 transactions was taken, yielding an average of $14.92 with a standard deviation of $5.51. (a) Which hypotheses should be used to show the manager's claim is correct? H0: p = 14.92 vs. Ha: p > 14.92 H0: p = 13.65 vs. Ha: p > 13.65 H0: μ = 13.65 vs. Ha: μ > 13.65 H0: μ = 14.92 vs. Ha: μ > 14.92 (b) Find the test statistic: (Use 4 decimals.) (c) What is the p-value? (Use 4 decimals.) (d) What is the conclusion of the hypothesis test, for α = 0.05? --- the value $13.65. There is --- evidence the mean transaction value is greater than $13.65. (e) Regardless of your conclusion above, what is the meaning of a Type II error in this context? you conclude the average transaction value is greater than $13.65, in reality the average transaction value is greater than $13.65. You conclude the average transaction value is equal to $13.65, in reality the average transaction value is equal to $13.65. You conclude the average transaction value is greater than $13.65, in reality the average transaction value is equal to $13.65. You conclude the average transaction value is equal to $13.65, in reality the average transaction value is greater than $13.65.
Answer:
A) Null Hypothesis; H0: μ = 13.65
Alternative hypothesis; Ha: μ > 13.65
B) t = 1.42
C) The p-value is greater than the significance level of 0.05. Thus, we fail to reject the null hypothesis and conclude that there is insufficient evidence to support the claim that the mean transaction value is greater than $13.65.
D) type II error will be to conclude the average transaction value is equal to $13.65, in reality the average transaction value is greater than $13.65.
Step-by-step explanation:
We are given;
Population mean; μ = $13.65
Sample mean; x¯ = $14.92
Sample standard deviation; s = $5.51
Sample size; n = 38
DF = n - 1 = 38 - 1 = 37
Significance level; α = 0.05
A) The hypotheses is defined below;
Null Hypothesis; H0: μ = 13.65
Alternative hypothesis; Ha: μ > 13.65
B) Since we are given sample standard deviation, we will use formula for t-value. Formula for the test statistic is;
t = (x¯ - μ)/(s/√n)
t = (14.92 - 13.65)/(5.51/√38)
t = 1.42
C) From online p-value from t-score calculator attached, using; t = 1.42, α = 0.05, DF = 37, one tail, we have;
P-value = 0.08199
D) The p-value is greater than the significance level of 0.05. Thus, we fail to reject the null hypothesis and conclude that there is insufficient evidence to support the claim that the mean transaction value is greater than $13.65.
E) A type II error simply means accepting a null hypothesis that is not true.
Now, in this case what it will mean is to accept the null hypothesis.
Thus, type II error will be to conclude the average transaction value is equal to $13.65, in reality the average transaction value is greater than $13.65.
What number equals 2 4/5?

Square root to the nearest tenth √1.001 ,√1.1212 ,√2.895, √4.005 ,√6.2533
Answer:
1.0 ; 1.1 ; 1.7 ; 2.0 ; 2.5
Step-by-step explanation:
Given the following :
√1.001 ,√1.1212 ,√2.895, √4.005 ,√6.2533
The square root to the nearest tenth :
Using calculator :
√1.001 = 1.0004998 = 1.0
√1.1212 = 1.0588673 = 1.1
√2.895 = 1.7014699 = 1.7
√4.005 = 2.0012496 = 2.0
√6.2533 = 2.5006599 = 2.5

What volume,in cubic inches,is equivalent to 15 cubic feet?
Answer: 1 feet = 12 inches
1 cubic feet = 12^3 = 1728 cubic inches
15 cubic feet = (15)(1728) = 25,920 cubic inches
Solution of the equation
Answer:
B
Step-by-step explanation:
The sides are not equal. You substitute the coordinates into the equation which gives you -11=-4 x 3
which solves to -11 = -12
therefore the sides are not equal

You plan on using cost-based pricing. The cost of your product is $10, and you are planning a 30% mark-up. What should the price of your product be?
Answer:
Selling price= $13
Step-by-step explanation:
Giving the following information:
The cost of your product is $10, and you are planning a 30% mark-up.
The price of the product is calculated by adding to the manufacturing costs a predetermined percentage.
Selling price= 10*1.3
Selling price= $13
Based on the cost of the product and the mark-up, the price of the product will be $13.
Price of productThis can be fund using the formula:
= Cost of product x ( 1 + markup percentage)
Solving gives:
= 10 x ( 1 + 30%)
= 10 x 1.3
= $13
In conclusion, the product would be $13.

Given a right triangle with sides of length a, b, and c and area a²+b²-c², find c/b, the ratio of the legs of the right triangle.
Answer:
4
Step-by-step explanation:
Looking at the sketch we can formulate 2 equations:
Pythag: [tex]b^{2} +c^{2} =a^{2}[/tex]
Area of triangle= [tex]\frac{1}{2} bc[/tex]
But area also = [tex]a^{2} +b^{2} -c^{2}[/tex] (from the question)
Therefore [tex]\frac{1}{2} bc[/tex] = [tex]a^{2} +b^{2} -c^{2}[/tex]
But we can sub in the expression for [tex]a^{2}[/tex] from pythag. ([tex]b^{2} +c^{2} =a^{2}[/tex])
[tex]\frac{1}{2} bc= b^{2} +c^{2} +b^{2} -c^{2}[/tex]
[tex]\frac{1}{2} bc=2b^{2}[/tex]
[tex]bc=4b^{2}[/tex]
[tex]c=4b[/tex]
[tex]c/b= 4b/b=4[/tex]
