In: Statistics and Probability
Two computer users were discussing tablet computers. A higher proportion of people ages 16 to 29 use tablets than the proportion of people age 30 and older. The table below details the number of tablet owners for each age group. Test at the 1% level of significance. (For subscripts let 1 = 16-29 year old users, and 2 = 30 years old and older users.)
16–29 year olds | 30 years old and older | |
---|---|---|
Own a Tablet | 69 | 231 |
Sample Size | 620 | 2,302 |
