According to a publication, 12.3% of 18 to 25 dash year dash olds were users of marijuana in 2000. A recent poll of 1293 randomly selected 18 to 25 dash year dash olds revealed that 176 currently use marijuana. At the 5% significance level, do the data provide sufficient evidence to conclude that the percentage of 18 to 25 dash year dash olds who currently use marijuana has changed from the 2000 percentage of 12.3%? Use the one-proportion z-test to perform the appropriate hypothesis test, after checking the conditions for the procedure. What are the hypotheses for the one-proportion z-test? Upper H 0: pequals nothing; Upper H Subscript a: p ▼ greater than not equals less than nothing (Type integers or decimals.)

A recent poll of 2500 randomly selected 18-25-year-olds revealed
that 290 currently use marijuana or hashish. According to a
publication, 12.5 % of 18-25-year-olds were current users of
marijuana or hashish in 1997. Do the data provide sufficient
evidence to conclude that the percentage of 18-25-year-olds who
currently use marijuana or hashish has changed from the 1997
percentage of 12.5 %? Use α=0.01 significance level.

who check Facebook before getting out of bed in the morning is at
least 36% and justify your answer.
b) Find the 75th percentile, and express it's meaning in a
complete sentence.
