Answer:
9,450
Step-by-step explanation:
10 cant go into the others because they end with a 5
Answer D.) There are no outliers, sorry if i’m wrong.
Female: Male:
60 35
96 109
26 31
n₁=no. of entries=3 n₂=no. of entries=3
s₁=sample standard s₂=sample standard
deviation=35.005 deviation=43.924
x₁=sample mean=60.666 x₂=sample mean=58.333
Here s and x are calculated from calculator.
Now,
for significance level
1-α=90%
1-α=0.9
α=0.1
α/2=0.05
As population variances are unknown for both Male and female so the best suitable formula is
(x₁ - x₂) ± tα/2,v₁ *

........1
where v(degree of fredom)=(s₁²/n₁+s₂²/n₂)² / ((s₁²/n₁)²/n₁-1)+(s₂²/n₂)²/n₂-1))
by putting values
v=3.81026
From Statistics table,
See the t table at α/2=0.05 and v=3.81026
use interpolation as v value is not in the table,
3.81026-3/4-3 = x-3.182/2.776-3.182
x= 2.853
by putting values in eq. 1 we get
(60.666-58.333) ± (2.853)*
2.333 ± 92.516 is the correct answer.
Answer:
66
Step-by-step explanation:
you have to find the median, and then find the median within the second half of the median
Median : 61
Now, look at 61, and look at 74. What is the median of those numbers in this set?
Q₂ = 66
Answer:
3
Step-by-step explanation:
(given) -8 = 2x - 14
(add 14 to both sides) 6 = 2x
(divde both sides by 2) 3 = x
