Reject Ho (sample was unusual so we reject Ho) There . is. sufficient evidence at the 5% level of significance to suggest that the mean bat’s range is more than 35 cm. In the event that we were performing a two-tailed test here, which we are not, , we would multiply the probability by 2 (just like we did in section 3). pvalue = (Practice 1)

25. In a study of the coliform contamination in streams, an environmentalist finds that one region has Normally distributed coliform levels (number of cells per 100 mL) with a mean of 122 and a standard deviation of 14. For a randomly selected sample, find the probability that the coliform level differs from the mean by more than 25. 26.

The power is a probability and it is defined to be the probability of rejecting the null hypothesis when the alternative hypothesis is true. After plugging in the required information, a researcher can get a function that describes the relationship between statistical power and sample size and the researcher can decide which power level they ...
