Aretailer maintains a web site that it uses to attract shoppers. the average purchase amount is $80. the retailer is evaluating a new web site that would, it hopes, encourage shoppers to spend more. let μ represent the average amount spent per customer at its redesigned web site. 11. the appropriate null hypothesis for testing the probability of the new design is h0: μ≤ 80. 12. if the α-level of the test is 0.05, then there is at most a 5% chance of incorrectly rejecting h0. 13. if the p-value of the test of h0 is less than α, then the test has produced a type ii error. 14. if the test used by the retailer rejects h0 with the α-level set to 0.05, then it would also reject h0 with the α= 0.01. 15. the larger the sample size used to evaluate the new design, the smaller the chance for a type ii error. 16. if the t-statistic rejects h0, then we would also reject h0 had we obtained the p-value using a normal distribution rather than a t distribution.

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
