Bumblebee bat is known to have mean weight of 1.8 g. A researcher found a group of bumblebee bat at Statopia, and take a sample of size 36 bats found an average of 1.905 and standard deviation is 0.42. Is there sufficient evidence to show the average weight of bumblebee bat at Statopia is bigger than 1.8g at 0.05 significance level based on sample?
