Answer:
- the sample mean is 44
- the sample standard deviation is 12.35
Step-by-step explanation:
given information:
data, 
= 36.45, 67.90, 38.77, 42.18, 26.72, 50.77, 39.0, 50.23
the number of data, n = 8
the sample mean, xbar
xbar = ∑/n
= (36.45+67.90+38.77+42.18+26.72+50.77+39.0+50.23)/8
= 352.08/8
= 44
standard deviation, s
s = 
= 
= 
= 12.35
Answer:
16
Step-by-step explanation:
step 1: 3 x 7 = 21
so you're left with this 21-25/5
step 2: 25/5=5
left with 21-5
step 3: 21-5=16
16 should be the right answer, sorry if i'm wrong
Answer:
7,12,17,22,27
Step-by-step explanation:
You just plug in 1,2,3,4,5 as n and add your values
so 7+5(1-1)=7
7+5(2-1)= 12 and so on
Mean is when u add all the numbers up and then divide how many numbers there are e.g 22 + 1 + 3=
22+1+3=26 divide by 3=8.666666666666667
The vowels are A,E,I,O,U so 5 because if you add them together it’s 5
