5°C and –10°C

0°C and 10°C

20°C and 5°C

The temperature above and below the freezing points are 5°C and –10°C respectively. The correct option is B.

The temperature at which a liquid begins to solidify Melting point is the temperature at which the liquid and solid states of a substance are in equilibrium at atmospheric pressure. Water has a freezing point of 0° Celsius or 32° Fahrenheit.

The freezing point of the water is 0 degrees Celcius. It means that below 0 degrees like in negative temperature water becomes ice. Above 0 degrees Celcius the water remains in a liquid form.

Therefore, the temperature above and below the freezing points are 5°C and –10°C respectively. The correct option is B.

Garret studies number of hours sleep per night among students who have a grade point average of 3.0–4.0 versus students who have a grade point average of 2.0–3.0.

His theory is that students who get more sleep will have a higher grade point average than students who get less sleep because they are more rested and, therefore, better able to concentrate.

In his samples, the mean number of hours of sleep students with a grade point average of 3.0–4.0 received each night was 6.8. The mean number of hours of sleep students with a grade point average of 2.0–3.0 received each night was 6.4.

Assuming there are no outliers or skew, do the results support Garret's theory?

Select from the drop-down menus to correctly complete the statements.

Since the samples were large and randomly chosen, we can use the samples to understand the populations.

Because the sample mean for students with a grade point average of 3.0–4.0 is
