Answer:
90% confidence interval for the mean weight loss for the population represented by this sample assuming that the differences are coming from a normally distributed population is [1.989 ,13.5105]
Step-by-step explanation:
The data given is
Mean Std Dev
Before 177.25 29.325
After 169.50 22.431
Difference 7.75 8.598
Hence d`= 7.75 and sd= 8.598
The 90% confidence interval for the difference in means for the paired observation is given by
d` ± t∝/2(n-1) *sd/√n
Here t∝/2(n-1)=1.895 where n-1= 8-1= 7 d.f
and ∝/2= 0.1/2=0.05
Putting the values
d` ± t∝/2(n-1) *sd/√n
7.75 ±1.895 * 8.598 /√8
7.75 ± 5.7605
1.989 ,13.5105
90% confidence interval for the mean weight loss for the population represented by this sample assuming that the differences are coming from a normally distributed population is [1.989 ,13.5105]
Answer:
a = 10
Step-by-step explanation:
fill in the blank 10-6=4
check by adding 4 +6
have a nice evening :) :) :)
Answer:
Yes, the two ratios are proportional because they are the same ratio
Step-by-step explanation:
10/2=5
24/2=12
10/24=5/12
Answer:
the answer should be 22, if it isnt I'm sorry
Answer:
10+8+6=24 the ratio of taking the biographies to the science books are: 4:3
Step-by-step explanation:
That is the answer because 10+8+6= total 24 books
ratio of biographies= 24:8=3:1
ratio of science fiction= 24:6= 4:1
hence according axiom 1 ab × Ac= aa × BC
3:1×4:1= 4:3
