Ascientist who studies teenage behavior was interested in determining if teenagers spend more time playing computer games then they did in the 1990s. in 1990s, the average amount of time spent playing computer games was 10.2 hours per week. is the amount of time greater than that for this year? fifteen students were surveyed and asked how many hours they spent playing video games. the test statistics is equal to 2.822. what is the p-value?
- The amount of time greater than 10.2 hours for this year.
- The is 0.01358.
mean, X = 10.2 hours
sample, n = 15
using t distribution
test statistics = 2.822
= 2 x P( > test statistics)
= 2 x P( > 2.822)
= 2 x 0.00679
is less than 0.10 which indicates that the amount of time greater than 10.2 hours for this year.
the answer is a i belaeve atleast thats what my calculator just gfave me
