Answer:
Claim : men weigh of wild jackalopes is 69.9
The null hypothesis : H0 : μ = 69.9
Alternative hypothesis : H1 : μ ≠ 69.9
Test statistic = −2.447085
P value = 0.0174
Conclusion :
Fail to Reject the Null hypothesis
Step-by-step explanation:
From the question given :
The claim is that : mean weight of wild jackalopes is still the same as 10 years with a mean weight of 69.9 lbs.
The null hypothesis : H0 : μ = 69.9
Alternative hypothesis : H1 : μ ≠ 69.9
Using calculator :
Sample mean (x) = 66
Sample standard deviation (s) = 12.345
The test statistic t :
(x - μ) / (s/√n)
n = sample size = 60
(66 - 69.9) / (12.345 / √60)
t = −2.447085
P value at α 0.01, df = 59 is 0.0174
Since the p value is > 0.01, the result is not significant at 0.01. Therefore, we fail to reject the Null
Answer: 6 - k

Difference means subtraction
Answer:
21
Step-by-step explanation:
let n be the identical number, then
n² = 441 ( take the square root of both sides )
n = = 21
The the identical numbers are 21
Answer:
C) 24√2
Step-by-step explanation:
The distance between the points is the radius of the circle. Use distance formula:
d² = (x₂ − x₁)² + (y₂ − y₁)²
d² = (5 − 2)² + (2 − 5)²
d² = 3² + 3²
d = 3√2
The radius of the circle is 3√2. The diameter of the circle is 6√2, so the side length of the square is 6√2. Therefore, the perimeter is 24√2.
