Answer:
The size of file downloaded is <em>88 megabytes.</em>
Step-by-step explanation:
Given that:
Average rate of downloading the file =
Time taken to download =
Formula for the size of file downloaded =
Rate of downloading,
Time taken, = 110 seconds
To find:
Size of file downloaded in megabytes = ?
Solution:
First of all, let us apply the given formula to find the size of file downloaded:
Size of file downloaded =
Size of file downloaded = 800 kilobytes seconds 110 seconds =
<em>88000 kilobytes</em>.
Now, let us convert the unit kilobytes to megabytes to find the answer.
<em>Conversion formula:</em>
1000 kilobytes = 1 megabyte
Let us use unitary method to find the number of megabytes in 88000 kilobytes.
1 kilobytes = megabytes
88000 kilobytes = 88000 megabytes
<em>88 megabytes.</em>
Therefore, the size of file downloaded is <em>88 megabytes.</em>
Answer:
There is strong evidence that less than 87% of the orders are delivered in less than 10 minutes.
Decision rule: Reject the null hypothesis if (P-value < level of significance)
Test statistic z=-2.70
Decision: Reject the null hypothesis (0.003<0.010)
Step-by-step explanation:
In this question we have to test an hypothesis.
The null and alternative hypothesis are:
The significance level is assumed to be 0.01.
The sample of size n=80 gives a proportion of p=61/80=0.7625.
The standard deviation is:
The statistic z is then
The P-value is
The P-value (0.003) is smaller than the significance level (0.010), so the effect is significant. The null hypothesis is rejected.
There is strong evidence that less than 87% of the orders are delivered in less than 10 minutes.
Decision rule: Reject the null hypothesis if (P-value < level of significance)
Test statistic z=-2.70
Decision: Reject the null hypothesis (0.003<0.010)
