Question
Observation = 23 Residual Standard Error= 13.32 Tweet rate: mean =303.5 SD=357.7 Revenue: mean=25.1 SD=31 Intercept estimate coefficients= 1.1501 SD=3.6761 t-stat= 0.313 tweet rate: estimate=0.0788
Observation = 23
Residual Standard Error= 13.32
Tweet rate: mean =303.5 SD=357.7
Revenue: mean=25.1 SD=31
Intercept estimate coefficients= 1.1501 SD=3.6761 t-stat= 0.313
tweet rate: estimate=0.0788 SE=0.0079 t-stat= 9.923
What is the slope and intercept?
what is the SE when the tweet rate= 800?
when the tweet rate is 200, SD=13.631, what is the lower value of the 99% prediction interval?
