According to a very large poll in 2015. about 90% of homes in California had access to the internet. Market researchers want to test if that proportion is now higher, so they take a random sample of 100 homes in California and find that 96 of them have access to the internet.
The researchers will test H, : P = 0.90 versus H, :p > 0.90, where p is the proportion of homes in California that have access to the internet. Assuming that the conditions for inference have been met, calculate the test statistic for their significance test.
