horrorfan [7]

Answer:

The percent error is 27.27%

Step-by-step explanation:

I did this by using the formula actual-estimated value/actual value

In this case it would be 3.75/13.75 and I got .2727 and then had to multiply by 100 (to find percent not decimal form) and got 27.27%

According to government data, the probability that an adult was never in a museum is 15%. In a random survey of 10 adults, what
leonid [27]

Answer: 0.8202

Step-by-step explanation:

Probability an adult was never in a museum = probability of success = p = 15% = 0.15

To find probability that 2 or fewer of the 10 samples selected were never in a museum is given by:

P(X=2) or P(X=1) or P(X=0).

Where

P(X=r) = nCr * p^r * q^n-r

and n=10, p =0.15, q=0.85

When r = 2

P(X=2) = 10C2 * 0.15² * 0.85^8 = 0.2759

When r = 1

P(X=1) = 10C1 * 0.15 * 0.85^9 = 0.3474

When r = 0

P(X=0)= 10C0 * 0.15^0 * 0.85^10 = 0.1969

Hence probability of having 2 or fewer adults who never visited the museum = 0.1969 + 0.3474+ 0.2759 = 0.8202
