Estimate the indicated probability by using the normal approximation as an approximation to the binomial distribution. (PROBLEMS

S_A_V [24]

Answer:

$P(X \ge 219 ) = 0.093$

$P(X \ge 219 ) = 0.1038$

Step-by-step explanation:

From the question we are told that

The percentage of hair dryers that are defective is p=2% $= 0.02$

The sample size is $n =10000$

The random number is x = 219

The mean of this data set is evaluated as

$\mu = n* p$

substituting values

$\mu = 10000 * 0.02$

$\mu =200$

The standard deviation is evaluated as

$\sigma = \sqrt{[\mu (1 -p)]}$

substituting values

$\sigma = \sqrt{[200 (1 -0.02)]}$

$\sigma = 14$

Since it is a one tail test the degree of freedom is

df = 0.5

$x_l = x- 0.5$

$x = 219 - 0.5$

$x = 218.05$

Now applying normal approximation

$P(X \ge 219 ) = P(z > \frac{x - \mu}{\sigma} )$

substituting values

$P(X \ge 219 ) = P(z > \frac{218.5 - 200}{14} )$

$P(X \ge 219 ) = P(z > 1.32} )$

From the z-table

$P(X \ge 219 ) = 0.093$

Considering Question 5

The random number is x = 90

The mean is $\mu = n * p$

Where n = 100

and p = 0.85

$\mu = 0.85 *100$

$\mu = 85$

The standard deviation is evaluated as

$\sigma = \sqrt{[\mu (1 -p)]}$

substituting values

$\sigma = \sqrt{[85 (1 -0.85)]}$

$\sigma = 3.5707$

Since it is a one tail test the degree of freedom is

df = 0.5

Now applying normal approximation

$P(X \ge 90 ) = P(z > \frac{x - \mu}{\sigma} )$

substituting values

$P(X \ge 219 ) = P(z > \frac{89.5 - 85}{3.5707} )$

$P(X \ge 219 ) = P(z > 1.2603} )$

From the z-table

$P(X \ge 219 ) = 0.1038$

I need help asap please explaining how u got that answer I'm struggling.

Natali5045456 [20]

my answer is 232.2 i got it by adding 50, 220, 250, 410 which would be 930 and then you divide it by 4 because that is how many numbers there are so the answer would be 232.2 that is the average.

hope this helps if that is what the question asked.
