The consumption of milk by individuals of a population is normally distributed. If you are a member of this population consuming milk, then: 1. If you have a standard score of Z = 2, what percentage of the population has scores greater than you? 2. If you have a standard score of Z = - 2, what percentage of the population has scores greater than you? 3. If you have a standard score of Z = 1, what percentage of the population has scores less than you? 4. If you have a standard score of Z = 1, what percentage of the population has scores farther away from the population mean (in either direction) than you? 5. If you have a standard score of Z = -1.7, what percentage of the population has scores farther away from the population mean (in either direction) than you? 6. If you have a standard score of Z = -1.7, what percentage of the population has scores greater than you?

1. 2.28%

2. 97.72%

3. 84.13%

4. 31.74%

5. 8.92%

6. 95.54%

Explanation:

1. A z score of 2 means has a proportion of the population of 0.9772 below

Therefore, the percentage of the the population that have an higher score = (1-0.9772)×100 = 2.28%

2. A z score of -2 means the percentage of the the population that have an higher score = (1-0.0228)×100 = 97.72%

3. A z score of 1 means the percentage of the the population that have a lesser score = (0.8413)×100 = 84.13%

4. A z score of 1 means the percentage of the the population that have a higher score = (1-0.8413)×100 = 15.87%

The population that have a lesser z score than -1 = 0.1587×100 = 15.87%

Therefore. the total percentage of the population that has scores farther away from the population mean in either direction = 2 × 15.87 = 31.74%

5. Where the z score = -1.7, we have;

The proportion lesser = 2×0.0446×100 = 8.92%

6. The percentage of the population that has a z score > -1.7 is presented as follows;

The proportion that have a z-score<-1.7 = 0.0446

Therefore, the proportion of the population that have a z-score more than -1.7 = 1 - 0.0446 = 0.9554

Hence the percentage of the population that has a higher z-score = 100×0.9554 = 95.54%.

answer:

i don't believe the ocean is purple, but it might once have been:

as for the sky, according to nasa:

"sunlight reaches earth's atmosphere and is scattered in all directions by all the gases and particles in the air. blue light is scattered more than the other colors because it travels as shorter, smaller waves. this is why we see a blue sky most of the time."
