Answer: Test statistic = -8 and rejected region is (-∞,-1.966) and (1.966, ∞)
Step-by-step explanation:
Since we have given that
X is the length of a rod.
Sample Mean = 2 inches
Standard deviation = 0.5 inches
n = 400
Hypothesis are
Test statistics would be
Degrees of freedom = n-1 =400-1 =39
and 
Using the t-distribution table, we get that critical value z = 1.966
Since the two tail test will be applied to this,
So, the acceptance region will be (-1.966, 1.966)
Hence, the rejected region will be (-∞,-1.966) and (1.966, ∞)
The square root of 7: 2.64575
-0.3
(-7/4)= -1.75
0.1
Square root of3: 1.73205
greatest to least: (-7/4), -0.3, 0.1, square root of 3, square root of 7
2941526 mi^2
The first thing you should know to solve this problem is the following conversion:
1mi = 1609.34m
Applying the conversion we have:
2941526 * (1609.34 / 1) ^ 2 = 7.61848E + 12 m ^ 2
Answer:
The land area of Australia in square meters is:
7.61848E + 12 m ^ 2
Step-by-step explanation:
1. $10.20/6 = 1.7 = the amount Michael receives for 1 pound of blueberries
2. We know that for 12 pounds he will receive $20.40 and if we do 1.7*4 for the remaining four pounds then do $20.40 + (1.7*4) = $27.20, D
Answer:
In case of true false questions there are two ways to answer each questions and we have 10 questions . So as per the rule of permutation we have (2×2×2×2×2×2×2×2×2×2) or 2^10 or 1024 no. Of ways to answer 10 true false questions in the exam.
