It's 4 because 36 divided by 9 it's 4 or 9 times 4 it's 36

The Ohio Department of Agriculture tested 203 fuel samples across the state in 1999 for accuracy of the reported octane level. F

Answer:

The Sample size is 1918.89035

Step-by-step explanation:

Consider the provided information.

It is given that 14 out of 105 samples failed.

Therefore p = 14/105 = 0.13 3... and q=1-0.133=0.867

Samples would be needed to create a 99 percent confidence interval.

Subtract the confidence level from 1, then divide by two.

$\frac{(1 -0.99)}{2}=0.005$

By standard normal table z=2.5758≈2.58

Calculate the sample size as:

$n=\frac{z^2pq}{e^2}$

Where, e is the margin of error,

Substitute the respective values.

$n=\frac{(2.58)^2(0.133)(0.867)}{(0.02)^2}=1918.89$

Hence, the Sample size is 1918.89035

The freezing point of water is 0 C. Scientists use positive numbers to show temperatures above the freezing point water and nega

inn [45]

Answer:

The -18°C temperature as the freezing point of maple syrup means that the temperature at which maple syrup changes from liquid to solid (that is, freezes) is 18° below the freezing point of water.

Step-by-step explanation:

It is explained that the freezing point of water is used as the standard or reference point to calibrate the Celsius scale.

The scientists use 0°C to represent the freezing point of water and subsequently use positive numbers to indicate temperatures above the freezing point of water and negative numbers to indicate temperatures lower than the freezing point of water.

So, a temperature/freezing point of -18°C simply means that the temperature/freezing point is 18° lower than the freezing point of water.

Hope this Helps!!!
