Let's imagine that we turn the machine on 100 times. (this will make the percent conversion easier)
the chance that works in the morning is 50% of 100 so it will work 50 times.
the chance that it will then continue for the rest of the day is 15% so 15%*50 (the number of times it worked), which is 7.5 times.
our times actually represented percent, so the answer is : 7.5%!
Answer:
the sample proportion is higher
Step-by-step explanation:
What we must do is calculate the proportion of the population, we are left with the fact that out of 38 students 58% have cell phones, these are the proportion of the population, then they would be:
38 * 58% = 22.04 students
Now, the sample proportion is 24.
Therefore 22.04 < 24
Which means the sample proportion is higher
