If Alpha = 0.05,
1. What is the critical t-value?
2. What is the decision for a statistically significant change in average weights at birth at the 5% level of significance?
Answers
Answer:
1. Critical value t=±2.447
2. The null hypothesis is failed to be rejected.
At a significance level of 0.05, there is not enough evidence to support the claim that the birth weight significantly differs from 6.6 lbs.
Step-by-step explanation:
This is a hypothesis test for the population mean.
The claim is that the birth weight significantly differs from 6.6 lbs.
Then, the null and alternative hypothesis are:
The significance level is 0.05.
The sample has a size n=7.
The sample mean is M=7.56.
As the standard deviation of the population is not known, we estimate it with the sample standard deviation, that has a value of s=1.18.
The estimated standard error of the mean is computed using the formula:
Then, we can calculate the t-statistic as:
The degrees of freedom for this sample size are:
For a two-tailed test with 5% level of significance and 6 degrees of freedom, the critical value for t is ±2.447.
As the test statistic t=2.152 is under 2.447 and over -2.447, it falls in the acceptance region, so the effect is not significant. The null hypothesis is failed to be rejected.
At a significance level of 0.05, there is not enough evidence to support the claim that the birth weight significantly differs from 6.6 lbs.

Answer:
Well, we know that there exists a function f(x) such that f(x-1) is a direct transformation of its parent function. First we want to set x=x-1. Conceptually, it might be easier just to annotate one of the x’s as a completely different variable, because we know that x doesn’t equal x-1. So let’s rewrite as x=y-1 and solve for y.
We now have y=x+1 where y(x) is actually our parent function and y(x)=f(x+1). So take our equation f(x-1) and substitute each x with (x+1). So f(x)=2(x+1) + 3
f(x)= 2x + 5. We can check this by finding f(x-1) because it should equal 2x+3.
f(x-1)= 2(x-1) + 5
f(x-1)= 2x + 3.

5 years repayment 11 years maintenance and electricity cost of $24.25
and $0.14, makes the total lifetime cost of the stove b. $2,166.53.
How can the total cost of the stove be calculated?
The cost of the stove = $986
Daily electricity cost = $0.14
Maintenance cost per year = $24.25
Annual Percentage Rate, APR, on the credit card = 9.26%
Number of years the balance was paid off = 5 years using identical monthly payments
Sales tax = 8.22%
Required:
Lifetime total cost of the stove
Solution:
Where;
r = 0.0926
n = 12 × 5 = 60
P = 1.0822 × $986 = $1,067.0492
Which gives;
Payment for the purchase ≈ 60 × $22.29 = $1337.4
Amount paid as electricity bill = $0.14 × 365 + 2 × $0.14 = $562.38
The maintenance cost = 11 × $24.25 = $266.75
Which gives;
- Total stove cost ≈ $1,337.4 + $562.38 + $266.75 = $2,166.53
The selection that gives the total cost is the is the option;
b. $2,166.53

Answer:
2166.53
Step-by-step explanation:
Price x 1.0822 = 1067.0492 <Price with tax
P= PV x i / 1- (1+i)^-n
^ x (identical monthly payments for 5 years aka 12 x 5)
average cost for electricity x (365 x years aka 11)
cost for maintenance x 11

The volume of the tower is 224 in³, which is not listed among the given options.
To find the volume of the rectangular block, we need to multiply its length, width, and height. Therefore, the volume of the single block is:
8 x 3.5 x 2 = 56 cubic inches.
Since we are stacking four blocks to create a tower, we need to multiply the volume of a single block by 4.
Thus, the volume of the tower is:
56 x 4 = 224 cubic inches.
The volume of a rectangular block can be found using the formula,
V = length × width × height.
In this case, the length is 8 inches, the width is 3.5 inches, and the height is 2 inches.
V = 8 × 3.5 × 2 V
= 28 × 2 V
= 56 in³
Now that we know the volume of one block, we can find the volume of the tower created by stacking four blocks. Tower volume = block volume × number of blocks Tower volume = 56 in³ × 4 Tower volume = 224 in³
