Answer: c. There is sufficient evidence to support the claim μ < 104.
Step-by-step explanation:
Let [tex]\mu[/tex] be the population mean.
Given : The mean score for all NBA games during a particular season was less than 104 points per game.
It indicates for  Alternative hypothesis : [tex]H_a:\mu<104[/tex]
If null hypothesis is rejected then it means we get sufficient evidence to support alternative hypothesis.
i.e. There is sufficient evidence to support the claim μ < 104.
Hence, the correct answer =  c. There is sufficient evidence to support the claim μ < 104.
