Damage to grapes from bird predation is a serious problem for grape growers. An article reported on an experiment involving a bird-feeder table, time-lapse video, and artificial foods. Information was collected for two different bird species at both the experimental location and at a natural vineyard setting. Consider the following data on time (sec) spent on a single visit to the location. (Note: Assume the populations are normally distributed.) Species Blackbirds Blackbirds Silvereyes Silvereyes o о но на-Н2 = 0 Hai H1 H₂ <0 sec (a) Calculate an upper confidence bound for the true average time that blackbirds spend on a single visit at the experimental location.

The data suggests the true average time spent by blackbirds at the experimental location exceeds that of blackbirds at the natural location. O Fail to reject Ho. The data suggests the true average time spent by blackbirds at the experimental location does not exceed that of blackbirds at the natural location. Reject Ho. The data suggests the true average time spent by blackbirds at the experimental location does not exceed that of blackbirds at the natural location. Reject Ho. The data suggests the true average time spent by blackbirds at the experimental location exceeds that of blackbirds at the natural location.
