Question

A scientist 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? Ten students were surveyed and asked how many hours they spent playing video games. The test statistics is equal to 0.45. What is the p-value?

between 0.001 and 0.005

less than 0.001

greater than 0.10

between 0.005 and 0.010

between 0.025 and 0.05

between 0.010 and 0.025

between 0.05 and 0.10

Explanation / Answer

H0:Mu=10.2

H1:Mu>10.2

Test statistic:

t=0.45 (since n is small)

P value=0.3317

Hence P is greater than 0.10
