anyanavicka [17]

Answer:

p value = 0.3122

Step-by-step explanation:

Given that Pedro thinks that he has a special relationship with the number 3. In particular,

Normally for a die to show 3, probability p = \frac{1}{6} =0.1667

Or proportion p = 0.1667

Pedro claims that this probability is more than 0.1667

H_0 = P =0.1667______H_a = P>0.1667_____

where P is the sample proportion.

b) n=30 and P = 6/30 =0.20

Mean difference = 0.2-0.1667=0.0333

Std error for proportion = \sqrt{\frac{p(1-p)}{n} } \\=0.0681

Test statistic Z = p difference/std error =  0.4894

p value = 0.3122

p >0.05

So not significant difference between the two proportions.

Organizers of an outdoor summer concert in Toronto are concerned about the weather conditions on the day of the concert. They wi
Kobotan [32]

Answer:

The value of the expected profit from the concert is 8,910

Step-by-step explanation:

Profit on a clear day X₁ = 36,000 with  13% probability.  

i.e  X₁ = 36000

    P(X₁) = 0.13

Profit on a cloudy day = 17,000 with 39% probability.

i.e  X₂ = 17000

    P(X₂) = 0.39

else,

loss of 5,000 if it rains with the probability of 48%.

i.e  X₃ = 5000

    P(X₃) = 0.48

The value of the expected profit from the concert is obtained as follows

Expected Value = (36,000*0.13) + (17,000*0.39) - (5,000*0.48)

                           = 4,680 + 6,630 - 2,400

                           = 8,910

1) A square has a side length of 10 inches. What is the perimeter?
antiseptic1488 [7]

Answer:

1) 40

2)9x-12

3)42

Step-by-step explanation:

1) A square has 4 sides, and if one side's length is 10, the perimeter (distance around the square) is 10 times 4=40

2) Simply add these values together to get 9x-12

3) Plug in 6 as x in 9x-12. (6*9)-12=54-12=42
