Based on this dotplot and the sample of 25 online
news readers, which conclusion can be drawn?
An online news report claims that 50% of online news
readers work in the business industry. To test this
claim, a researcher takes an SRS of 25 online news
readers. Nine of them work in the business industry A
simulation of 65 trials was conducted under the
assumption that 50% of online news readers really do
work in the business industry
Online Readers and
the Business Industry
20
O Since 0 36 of the sample works in the business
industry, 0 36 is the true probability that an online
news reader works in the business industry
0 it is most likely that out of 25 online readers,
between 12 and 13 work in the business industry
Because there appear to be outliers present that
are greater than 16, we can conclude that more
than 50% of online readers work in the business
industry
There is about a 0046 chance that 9 or fewer
online readers work in the business industry. This is
unusual and is convincing evidence that less than
50% of online readers work in the business
industry
Frequency
