Describe the sampling distribution of p(hat). Assume the size of the population is 30,000.n=800, p=0.6a) Determine the mean of t
Leno4ka [110]

Answer:

Standard deviation of the binomial distribution

                               = \sqrt{n p q} = \sqrt{192}  = 13.856

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given size 'n' = 800

The population proportion 'p'=0.6

Let 'X' be the random variable of the binomial distribution

a)  mean of the binomial distribution  = n p = 800 ×0.6

                                                             μ  = 480

b)  variance of the binomial distribution

                                                                      = n p q

                                                                      =  800 X 0.6 ×0.4

                                                                 σ²  = 192

Standard deviation of the binomial distribution

                                                             σ    = \sqrt{n p q} = \sqrt{192}  = 13.856

4. Amori sold 25% of her daily goal. She had sold $600 worth of merchandise.
insens350 [35]

in short, 25% is just 1/4 of anything, we know she's sold 25% which is $600, so her daily goal must be 1/4 + 1/4 + 1/4 + 1/4, or namely 600 + 600 + 600 + 600 = 2400.

Will give branliest and 10 points please answer with correct work
insens350 [35]

Answer: Part A the answer is yes and Part B the answer is no.

Step-by-step explanation:

Part A when you divide 7 by 2 you get 3.5 and if you multiply that number by the rest of the numbers and you get the number beneath the other number.

Part B when you divide 8 by 5 you get 1.6 and if you multiply that number by the rest of the numbers and then you don't get the number beneath the other number.
