First Data Corp. records indicate that in 2005, 43% of adult email users received a phishing email. A phishing email replicates an authentic site for the purpose of stealing personal information such as account numbers and passwords. Suppose a random sample of 800 adults will be surveyed on whether they have received phishing emails to determine recent trends. Give the mean of the sample distribution of LaTeX: \hat{p}p ^. Give your answers in decimal form and round to two decimal places. (Example: 0.39)

The answer is 0.43

Step-by-step explanation:

Given:

43 percentage (43%) of the adult users received a phishing e - mail

Total numbers of adult selected at random for phishing e - mail  = 800

Solution

Let Y represent Total numbers of adults sampled at random

Let X represent the number of adults that received

:. X = 43% of Y

43% of 800

=   x 800  = 344.

mean = =

mean of the sample distribution  = 0.43

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
