A fish hatchery manager has two ponds containing largemouth bass, a predatory fish. The bass in Pond A were supplied with small fish (40-60 mm in length) to serve as a supplemental food source; the bass in Pond B were not. The manager would like you to determine if the supplemental feeding improved the growth rates of the bass. He graciously agreed to provide the following data taken from a random sample of fish from each pond.
Perform the appropriate tests to help this cooperative fellow determine whether feeding influenced growth rates.
POND A AND POND 2 ARE TWO INDEPENDENT SAMPLES.WE WILL CARRY OUT INDEPENDENT T TEST.
NULL HYPOTHESIS H0:
ALTERNATIVE HYPOTHESIS Ha:
Level of significance =0.05
By using data analysis tool pack of EXCEL we have
Test statistic t
Degrees of freedom= 34
P value=0.044
Since P value SMALLER than 0.05 therefore SIGNIFICANT
Decision: REJECT H0.
Conclusion: We have sufficient evidence to conclude that feeding influenced growth rates at 0.05 level of significance.
