Answer:
6+2+3+3+3+5=22 is a correct answer
Answer:
Test statistic = 1.664
Step-by-step explanation:
The hypothesis :
H0 : μ = 47.2
H1 : μ ≠ 47.2
Given that :
Sample mean, xbar = 47
Sample size, n = 250
Standard deviation, σ = 1.9
The test statistic :
(xbar - μ) ÷ (σ/√(n))
T = (47 - 47.2) ÷ (1.9/√(250))
T = (0.2 / 0.1201665)
Test statistic = 1.664
Answer:
680
Step-by-step explanation:
14(-6x +10) - 16x - 100x + 140 for x = -2.
14(-6(-2) + 10) - 16(-2) - 100(-2) + 140
14(12 + 10) + 32 + 200 + 140
14(22) + 372
308 + 372
680
Answer:
C; P v q
Step-by-step explanation:
Here, we want to give the logical equivalent of the statements.
Firstly,
let p = memorial day is in July
q = parallel lines intersect
It should be noted that on logic, the term or can be represented by V
Thus, the statement here can be written as;
P V q
Answer:
The shorter range.
Step-by-step explanation:
When you think about the confidence interval you automatically think about how wide it is, in relation to its range. A typical confidence interval is generally 95%, however when it increases, it also increases the 'confidence' of the data and therefore its range.
Logically, a level of confidence of 85% will be much narrower than one of 90%, 95% or 99%, this implies that the wide range will be narrower than that of others. So things the 85% confidence interval in a multiple selection response, compared to the other three intervals, will always be the shortest.
