Answer:
4
Step-by-step explanation:
Because the fact the quits are ll feet there are 6 feet left over but that can not make 11 feet quilt
Given that the mean is $9.5 and the standard deviation is $1.30, the standard error will be given by:
σ/√n
where
σ-standard deviation
n=sample size
thus, we shal have:
1.30/√20
=0.2906
Next we find the margin error
0.2906*2=0.581
thus the confidence interval will be:
(9.5+0.581, 9.5-0.581)
=(10.081,8.919)
How many minutes did it take him to cover 1 mile? 5 minutes.
If you have for example
19.90$ you round it as 20
if u have 19.05 you have it as 19 only because its not near to the next number to it
