For this case, the arithmetic sequence is given by:
an = 17n-1
Let's check it:
First week:
n = 1:
a1 = 17 (1) -1
a1 = 17-1
a1 = 16
Second week:
n = 2:
a2 = 17 (2) -1
a2 = 34-1
a2 = 33
Third week:
n = 3:
a3 = 17 (3) -1
a3 = 51-1
a3 = 50
Answer:
the explicit rule for the arithmetic sequence that defines the number of boxes of cereal sold in week n is:
an = 17n-1
Solving an equation uses the formulas
Let
μ = population mean
σ = population std. deviation.
n = sample size.
At 95% confidence level, the confidence interval is
(μ - 1.96y, μ + 1.96y),
where y = σ/√n.
Therefore
μ - 1.96y = 6.5 (1)
μ + 1.96y = 12.5 (2)
Add (1 and (2) to obtain
2μ = 19
μ = 9.5
The calculated value of μ is within the interval (6.5, 12.5).
Answer:
The statement "There is a 95% probability that the true population mean is between 6.5 and 12.5" is True.
the following graph represents f(X)=X+2
Calculate the z-score of the given by the equation,
z-score = (x - m)/s
where x is the data point, m is the mean, and s is the standard deviation. Substituting the known values,
z-score = (11 - 8)/ 3 = 1
This translates to 0.84.
ANSWER: 0.84.
