Step-by-step explanation:
So, in this problem, we're given the size of the of the file. We are also given the rate of change of the amount-downloaded function.
Notice how the transfer rate is in units of time (25.2 MB/s means 25.2 MB per second).
If we want to calculate how <em>long</em> it'll take to download the entire file, we have to divide the file size by the amount of the MB downloaded in one second. (This is assuming the download rate is constant, in the case it isn't constant, you would use calculus) This will find the total number of seconds needed to download the entire file.
We're essentially solving for t in the equation

The hypothesis test is left-tailed.
Step-by-step explanation:
Given : The null and alternative hypotheses are
The parametric is being tested here is "p", where p stands for population proportion.
