Answer:
The 99% confidence interval of the population standard deviation is 1.7047 < σ < 7.485
Step-by-step explanation:
Confidence interval of standard deviation is given as follows;
s =
Where:
= Sample mean
s = Sample standard deviation
n = Sample size = 7
χ = Chi squared value at the given confidence level
= ∑x/n = (62 + 58 + 58 + 56 + 60 +53 + 58)/7 = 57.857
The sample standard deviation s = = 2.854
The test statistic, derived through computation, = ±3.707
Which gives;
1.7047 < σ < 7.485
The 99% confidence interval of the population standard deviation = 1.7047 < σ < 7.485.
<h3>Answer:</h3>
In this question, it's asking you to put the numbers that were given from <em>least </em>to <em>greatest.</em>
Our given numbers are:
- 0.35
Now, lets sort them out.
We know that negative numbers would be the least. Sicne there's only one negative number, we would put that first because it's the least out of the numbers.
would go next. To make it easier, we can turn it into a decimal.
when you divide.
0.35 will go next. This would be bigger than 0.15, but lower than the next number.
would go last, due to the fact that it's the greatest.
is the same as 1.75
When you put them in order, you should get
