The highest sum you would get with 2 dice rolls would be 6 + 6 = 12

so the probability of getting two numbers whose sum is less than 13 is 100%

Just multiply 20 by both sides.

n = 20(6/8)

Multiply that out and that is your answer :)

A student records the repair cost for 17 randomly selected stereos. A sample mean of $52.33 and standard deviation of $21.44 are
Dafna11 [192]

Answer:

90% confidence interval is (43.25, 61.41)

Step-by-step explanation:

Given that,

n = 17

Mean, \bar{x} = 52.33

Standard deviation, \sigma = 21.44

∝ = 0.10

Now,

Confidence interval = \bar{x}  ± t_{\frac{\alpha }{2}, n-1} [\frac{\sigma}{\sqrt{n} } ]

                                 = 52.33 ± 1.7646 [ 21.44 / √17 ]

                                 = 52.33 ± 9.0791

So,

52.33 + 9.0791  = 61.4091

52.33 - 9.0791  = 43.2509

So,

90% confidence interval is (43.25, 61.41)

Also,

Lower end-point = 43.25

Upper end-point = 61.41
