100. You would divide the original amount of crackers by 240, then multiply by the new amount of crackers.
Answer: 
Step-by-step explanation:
Given : sample size : n= 51
sample standard deviation : s= 0.46
Significance level : 
Using chi-square distribution, the critical values will be :


Confidence interval for population standard deviation (
) :

Substitute all the values , we get

Hence, the 95% two-sided confidence interval for σ : 
Answer:
Variance, Range, Standard deviation, Inter-quartile range
Step-by-step explanation:
The most commonly used measure of variability in a data set include;
Variance and standard deviation - measures the variability of a data set about a fixed location, the mean. Variance is the square of the standard deviation.
Range - this is the difference between the largest and the smallest values in a data set.
Inter-quartile range is simply the difference between the third and the first quartile where the second quartile is the median.
Other measures include;
Downside semi-variance
5 pounds
Because you have to subtract $80 from $39.30 and when you do that you get $40.70. Then you divide that by the $8.14 per pound and that gives you your answer.
