Answer:
C
Step-by-step explanation:
Using the Empirical Rule, the interval that contains 68% of the scores is [81.5, 90.5].
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
68% of the scores are within 1 standard deviation of the mean, hence the bounds of the interval are:

Answer:
Time with 4.2MB/S speed = 7314.3 seconds
Time with 900 KB/S speed = 34952.5 seconds
Step-by-step explanation:
Given that:
Internet download speed = 4.2 MB/S
File to download = 30 GB
1 GB = 1024 MB
30 GB = 30*1024 = 30720 MBS
Time required =
Time required = 7314.3 seconds
With 900 KB/S
1 MB = 1024 KB
30720 MB = 30720 * 1024 = 31457280 KBS
Time =
Hence,
Time with 4.2MB/S speed = 7314.3 seconds
Time with 900 KB/S speed = 34952.5 seconds
