45-2(h-1)<32

Step-by-step explanation:

This is a problem related to arithmetic progression. The formula we use is that of for nth term

$a_{n}=a+(n-1)d$

Here

$a=45 , d=-2 ,n=h , a_{n}=a_{h}$

$a_{h}=45+(h-1)(-2)\\a_{h}=45-2(h-1)\\$

Now we have to analyse a situation when our temperature comes below 32

$a_{h}$

This is our inequality

Solving this

45-2h

Hence in 8th hours the temperature will be below 32F

The sample should be larger to give more reliable information.

The sample size is too small to represent the population.

The sample size is too small and will show larger variation.

The sample size is too small and can lead to false inferences.
