The most accurate determination for the number of 45.36 feet per second Tyrone traveled on his way to work.
Given that,
Using a stopwatch Tyrone determines it takes him 58.2 minutes to travel 30 miles to work the stopwatch measures to hundredths of a minute going by the accuracy of the stopwatch.
We have to determine,
Which is the most accurate determination for the number of feet per second Tyrone traveled on his way to work?
According to the question,
Tyrone determines it takes him 58.2 minutes to travel 30 miles to work,
the stopwatch measures to hundredths of a minute going by the accuracy of the stopwatch are determined by,
Substitute the values in the equation,
If 1 mile = 5,280 feet, then his speed is,
And 1 minute = 60 seconds, then his speed is,
Hence, The most accurate determination for the number of 45.36 feet per second Tyrone traveled on his way to work.

Answer:
Step-by-step explanation:
We know that the mean and standard deviation of the sampling distribution of the sample proportion() is given by :-
, where p= Population proportion and n = sample size.
Let p be the proportion of blue chips.
As per given , we have
p= 0.275
n= 5
Now , the mean and standard deviation of the sampling distribution of the sample proportion of blue chips for samples of size 5 will be :
Hence, the mean and standard deviation of the sampling distribution of the sample proportion of blue chips for samples of size 5 are :
