ohaa [14]

Answer:

57

Step-by-step explanation:

I prefer the equation in this format

\frac{3 |m - 2 {n}^{2} | }{4}

substitute -4 for m and 6 for n

\frac{3 | - 4 - 2( {6}^{2}) | }{4}

square the 6 then multiply by 2

\frac{3 | - 4  - 72| }{4}

solve inside the absolute value then multiply by 3

\frac{3 | - 76| }{4}

\frac{228}{4}

divide by 4

Assume that adults have IQ scores that are normally distributed with a mean of mu equals 100 and a standard deviation sigma equa
aleksley [76]

Answer: 0.5467

Step-by-step explanation:

We assume that the test scores for adults are normally distributed with

Mean : \mu=100

Standard deviation : \sigma=20

Sample size : = 50

Let x be the random variable that represents the IQ test scores for adults.

Z-score : z=\dfrac{x-\mu}{\sigma}

For x =85

z=\dfrac{85-100}{20}\approx-0.75

For x =115                                                                                                                                            

z=\dfrac{115-100}{20}\approx0.75

By using standard normal distribution table , the probability the mean of the sample is between 95 and 105 :-

P(85

Hence, the probability that a randomly selected adult has an IQ between 85 and 115 =0.5467
