Alpha level is a probability value that is used to define the concept of "very unlikely" in a hypothesis. This value determines he boundaries for the critical region, which is composed of the extreme sample values that are very unlikely to be obtained if the null hypothesis is true. Type I error is <span>when a researcher rejects a true null hypothesis.</span>
The relationship between the alpha level, the size of the critical region, and the risk of a type i error is the following: when the alpha level increases, the critical region increases and type I error increases.

Answer:
B. $6,448,519
Explanation:
The computation of the present value of this growing annuity is given below:
PVA = [Cash flow at year 1 ÷ (interest rate - growth rate)] × {1 - [(1 + growth rate) ÷ (1 + interest rate)^number of years}
= [$675,000 ÷ (0.18 - 0.13)] × [1 - (1.13 ÷ 1.18)^15]
= $6,448,519
Hence, the correct option is b.
Answer:
Capability ratio = 1.04166
Explanation:
Given:
Length of a shoe (not deviate) = 1 mm
Standard deviation of this length = 0.32 mm
Number of standard deviations = 3
Find:
Capability ratio = ?
Computation:
Capability ratio = [Length of a shoe (not deviate) / Standard deviation of this length] / Number of standard deviations
Capability ratio = [1 / 0.32] / 3
Capability ratio = 3.125 / 3
Capability ratio = 1.04166
Capability ratio is greater than 1, therefore process is capable.
