The answer is 23/24. All of the denominators had to be the same number so I had to simplify 2/3 into a denominator of 24(options number): 2/3x8/8=16/24. Then, I multiplied 1/8x3/3 which is 3/24. Next, I simplified 1/6x4/4 which is 4/24 and I added all of those answers that is 23/24.

\frac{2}{3}  +  \frac{1}{8}  +  \frac{1}{6}  \\  =  \frac{2 \times 8}{24}  +  \frac{1 \times 3}{24}  +  \frac{1 \times 4}{24}  \\  =  \frac{16 + 3 + 4}{24}
=  \frac{23}{24}
First, we make all the denominator equal, through multiplication of the least common multiple. In this case, the LCM is 24: 3×8, 8×3, and 6×4. Then, we multiply each fraction by its corresponding multiplier. This comes out to be 16, 3, and 4, respectively. Add them up and it totals 23.

For a standardized psychology examination intended for psychology majors, the historical data show that scores have a mean of 52
Ludmilka [50]

Answer:

the probability that a sample of the 35 exams will have a mean score of 518 or more is <em> 0.934 </em>or<em> 93.4%</em>.

Step-by-step explanation:

This is s z-test because we have been given a sample that is large   (greater than 30) and also a standard deviation. The z-test compares sample results and normal distributions. Therefore, the z-statistic is:

(520 - 518) / (180/√35)

= 0.0657

Therefore, the probability is:

P(X ≥ 0.0657) = 1 - P(X < 0.0657)

where

  • X is the value to be standardised

Thus,

P(X ≥ 0.0657) = 1 - (520 - 518) / (180/√35)

                       = 1 - 0.0657

                       = 0.934

Therefore,  the probability that a sample of the 35 exams will have a mean score of 518 or more is <em>0.934 or 93.4%</em>.
