Answer:
D) 0.5764.
Step-by-step explanation:
According to a standard z-score table, a z-score of -0.5 corresponds to the 0.3085-th percentile of a standard normal distribution.
Furthermore, a z-score of 1.2 corresponds to the 0.8849-th percentile of a standard normal distribution.
Therefore, the area under the standard Normal curve corresponding to -0.5 < Z < 1.2 is:
![A = 0.8849-0.3085\\A=0.5764](https://tex.z-dn.net/?f=A%20%3D%200.8849-0.3085%5C%5CA%3D0.5764)
The answer is option D) 0.5764.
Answer:
c. 7.25
Step-by-step explanation:
Given the following information from an experiment:
![\left\begin{array}{ccc}&$Sample Size&$Sample Mean \\$Treatment 1&5&4\\$Treatment 2&10&8\\$Treatment 3&5&9\end{array}\right](https://tex.z-dn.net/?f=%5Cleft%5Cbegin%7Barray%7D%7Bccc%7D%26%24Sample%20Size%26%24Sample%20Mean%20%5C%5C%24Treatment%201%265%264%5C%5C%24Treatment%202%2610%268%5C%5C%24Treatment%203%265%269%5Cend%7Barray%7D%5Cright)
Total Sample Size =5+10+5=20
Therefore, the overall mean
![=\dfrac{(5 \times 4)+ (10 \times 8) + (5 \times 9)}{20} \\=\dfrac{145}{20}\\\\=7.25](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B%285%20%5Ctimes%204%29%2B%20%2810%20%5Ctimes%208%29%20%2B%20%285%20%5Ctimes%209%29%7D%7B20%7D%20%5C%5C%3D%5Cdfrac%7B145%7D%7B20%7D%5C%5C%5C%5C%3D7.25)
