During 2008, college work-study students earned a mean of $1478. Assume that a sample consisting of 25 of the work-study students at a large university was found to have earned a mean of $1503 during that year, with a standard deviation of $210.  If the null and alternative hypotheses can be used to suggest that the average earnings of this university’s work-study students were significantly higher than the national mean. At 5% level of significance what is your conclusion?       There is enough evidence to support the claim     There is no enough evidence to support the claim     There is enough evidence to reject the claim     There is no enough evidence to reject the claim
