The number of friends that can go ice skating is 5.
<h3>What is the total number of friends that can go ice-skating?</h3>
The total amount spent = cost of the group ticket + total cost of the hot chocolate + total cost of renting the skates
$38.75 = $10 + $4x + $1.75x
Where x represents the total number of friends.
In order to determine the total number of friends, take the following steps:
Combine similar terms
$38.75 - $10 = $4x + $1.75x
Add similar terms
$28.75 = $5.75x
Divide both sides of the equation by 3.75
x = 5

Considering the situation described, the scientist's null and alternative hypothesis are described by:
Null hypothesis
; Alternative hypothesis
.
<h3>What are the hypothesis tested?</h3>
At the null hypothesis, it is tested if there is no difference, that is, the difference of the means represented by
is of 0, hence:

At the alternative hypothesis, it is tested if there is a difference, hence:
