Answer:

Step-by-step explanation:

60 requests are made.

Spencer gets 25% of these requests. Convert this to a decmal (divide by 100) to get 0.25. 25% of 60 is:

(0.25)(60)=15\\

So Spencer gets 15 requests. Now do the same process for Tanvi:

(0.10)(60)=6

So Tanvi gets 6 requests. To find out how many more requests Spencer gets compared to Tanvi:

15-6=9

Therefore, Spencer gets 9 more requests than Tanvi.

A GROUP OF STATISTICS STUDENTS DECIDED TO CONDUCT A SURVEY AT THEIR UNIVERSITY TO FIND THE AVERAGE (MEAN) AMOUNT OF TIME STUDENT
Kay [80]

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

n = 240

mean = 22.3 hours

standard deviation = 6 hours

At 99% level of confidence, z = 2.58

So, interval would be

\bar{x}\pm z\dfrac{\sigma}{\sqrt{n}}\\\\=22.3\pm 2.58\times \dfrac{6}{\sqrt{240}}\\\\=22.3\pm 0.99\\\\=(22.3-0.99,22.3+0.99)\\\\=(21.31,23.29)

Hence, Option 'c' is correct.
