Answer:
B
Step-by-step explanation:
To construct a confidence interval estimate, the sample must be randomized. Hence option A is a requirement.
The data must follow normal distribution pattern or at least nearly normal distribution condition. Hence, option D is also a must for confidence interval estimate.
Normal distribution can be shown with a data with histogram graph with a bell-shaped showing a balanced proportion of data, hence option C is also true.
While option B with population skewed to the right shows negative distribution which will have mean to the right of the median. Hence B is not the requirement for confidence interval estimate for a population variance.
Winchester store charges $19 per charm, so if she uses 3 charms, the cost is 19*3, if she uses 5, the cost is 19*5, if she uses "c" charms, the cost of that will be 19*c or 19c. They also charge a fixed value of 47 bucks for the bracelet to put it on.
Winchester charges in total then 19c + 47
Kim store charges $18 for the charms, so if she uses 3 charms, that'd be 18*3, if she uses 7 charms, that'd be 18*7, if she uses "c" charms, that'd be 18c. They also charge 48 bucks for the bracelet.
Kim charges in total then 18c + 48.
if the costs "equal" each other, then
Part A:we know p(t)=6t and also
A(p)=πp2replace p by 6t
A(t)=π(6t)2=36πt2Part B = 7234.56
