Answer:
Option c. integers from 1 to 10 inclusive.
Step-by-step explanation:
The given sets are A = { 1, 3, 5, 7, 9 }
B = { 2, 4, 6, 8, 10 }
C = { 1, 5, 6, 7, 9 }
We have to determine A ∪ B
A ∪ B = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }
Therefore, A ∪ B is the set of all from 1 to 10 inclusive.
option C will be the answer.
Thats it the correct answer
Answer:
0.0698
Step-by-step explanation:
Given :
Population mean, μ = 20
Sample mean, xbar = 21.1
Sample standard deviation, s = 4.3
Sample size, n = 35
The hypothesis :
H0 : μ = 20
H0 : μ > 20
The test statistic :
(xbar - μ) ÷ (s/√(n))
T = (21.1 - 20) ÷ (4.3/√(35))
T = 1.1 ÷ 0.7268326
Test statistic = 1.513
Using the Pvalue calculator :
df = n - 1 = 35 - 1 = 34
Pvalue(1.513, 34) = 0.06976
Pvalue = 0.0698 (4 decimal places)
