Answer:
Step-by-step explanation:
First, convert the 4 mins into hours by dividing by 60;
4/60 =0.067
Add 0.067 to 75 hrs to get the total = 75+0.067 = 75.067
Therefore the total time Chris needs to make up for is 75.067 hrs
Total number of days Chris has = 25
Next,
IF in 25 days = he can cover 75.067hrs
then in 1 day he will cover = (1 * 75.067)/ 25
= 3.002
Therefore, Chris needs to do 3hrs each day to be able to complete the deadline
Answer:
The null hypothesis is
, in which x is the proportion tested.
The alternative hypothesis is 
Step-by-step explanation:
A recent article in a university newspaper claimed that the proportion of students who commute more than miles to school is no more than x.
This means that at the null hypothesis, we test if the proportion is of at most x, that is:

Suppose that we suspect otherwise and carry out a hypothesis test.
The opposite of at most x is more than x, so the alternative hypothesis is:

Answer:
1/5 to 1/5
Step-by-step explanation:
The output is the y value. So look at the plotted points and then take out the x values. Put the y values in order. The answer is the fourth answer choice.
