A sample of 1200 computer chips revealed that 31% of the chips fail in the first 1000 hours of their use. The company's promotional literature claimed that less than 34% fail in the first 1000 hours of their use. Is there sufficient evidence at the 0.05 level to support the company's claim?

In the data set shown below, what is the value of the quartiles?

{42, 43, 44, 44, 48, 49, 50}

A.Q1 = 43.5; Q2 = 44; Q3 = 49

B.Q1 = 43; Q2 = 44; Q3 = 48.5

C.Q1 = 43.5; Q2 = 44; Q3 = 48.5

D.Q1 = 43; Q2 = 44; Q3 = 49

Step-by-step explanation:

aloha~! my name is zalgo and i am here to you out on this gracious day. in order to compare the ratios easily, it is best that we simplify the question first. so, the cougars would have 6 wins for 5 losses, bobcats make 2 wins for 1 loss. bulldogs and tigers have a ratio where you can't simplify it. so, the team with the lowest rate would be the bobcats.

i hope that this ! : d

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
