Answer
The null hypothesis: Americans age 15 and older spend 1.22 hours per day eating and drinking.
The alternative hypothesis: Americans age 15 and older spend less than 1.22 hours per day eating and drinking.
P-value interpretation: the probability of the mean of any sample of size 50 to be equal or less then the mean of the researcher's sample of size 50, given that the population mean is 1.22, is 0.0329.
Work Step by Step
$H_0:~µ=1.22$
$H_1:~µ\lt1.22$
$P$-value $=0.0329$
