A scientist has read that the mean birth weight, , of babies born at full term is 7.3 pounds. The scientist, believing that u is less than this value, plans to perform a statistical test. She selects a random sample of birth weights of babies born at full term and finds the mean of the sample to be 7 pounds and the standard deviation to be 1.6 pounds. Based on this information, answer the questions below. What are the null hypothesis (H) and the alternative hypothesis (H ) that should be used for the test? Ho: His 7 H : u is 7 less than less than or equal to greater than In the co greater than or equal to Type I error? not equal to A Type I equal to the hypothesis that u is |7 w ? v when, in fact, u is ?

The scientist, believing that u is less than this value, plans to perform a statistical test. She selects a random sample of birth weights of babies born at full term and finds the mean of the sample to be 7 pounds and the standard deviation to be 1.6 pounds. Based on this information, answer the questions below. What are the null hypothesis (H.) and the alternative hypothesis (H, ) that should be used for the test? Ho: u is ? V ? H : His ? v ?
