Question 1 of 10, Step 1 of 1 0/10
Correct
A drug which is used for treating ADHD has potentially dangerous side effects if it is taken in doses which are larger than the required dosage for the treatment. A
medical researcher believes that the variance in dosage is different for two tablets made by different production facilities. The sample variance of a sample of 10
dosages of tablet "A" is 0.017. The sample variance of a sample of 13 dosages of tablet "B" is 0.002. Construct the 95% confidence interval for the ratio of the
population variances. Round your answers to four decimal places.

answer: a rhombus has two lines of symmetry that run through one vertex to the one directly across it. unlike a square, planes through the center of each edge of a rhombus do not yield mirrored sides.

step-by-step explanation:

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

the answer would be c:   ax + b = ax + c

step-by-step explanation:

step-by-step explanation:   divide the numerator by the denominator to get the decimal

it would still be 193

if divide by 100 then 1.93
