2 answers:
Answer:
j=m-10
Step-by-step explanation:
If j respresentst he time Jacob spent in the test and m the time Mark spent on the test. We can write an expression that shows the amount of Time Jacob spent on the test compare to Jacob:
We know that Jacob finished the test 10 minutes before Mark.
Let j equal the Total time Jacob spent in terms of Marks time is:
Jacob spends m-10 on the test compared to Mark

Answer:
(a) 1155.84
(b) 48.2%
(c) D
Step-by-step explanation:
The number of total responses is, <em>N</em> = 38,528.
(a)
It is provided that 3% answered with "a lot".
Compute the actual number of responses consisting of "a lot" as follows:
n (a lot) = N × P (a lot)
= 38528 × 0.03
= 1155.84
Thus, the actual number of responses consisting of "a lot" is 1155.84.
(b)
The number of responses consisting of "very little or none" is,
n (very little or none) = 18,566
Compute the percentage of responses consisted of "very little or none" as follows:
The percentage is: 0.482 × 100% = 48.2%.
Thus, the percentage of responses consisted of "very little or none" is 48.2%.
(c)
As the sample size increases the sample statistic value gets closer and closer to the actual population parameter value.
Thus, making the sample statistic an unbiased estimator of the population parameter.
And proving that the sample is a true representative of the population.
Thus, the correct option is (D).
