1) a severe storm has an average. Peak wave height of u= 16.4 feet for waves. Suppose that a reading of 30 waves showed an average wave height of x=17.3 feet. Previous severe storm indicate standard deviation = 3.5 feet. Use a = 0.01 A) what is the level of significance ___ B)what is the value of the sample test statistics (round your answer to two decimal places)___ 2) for healthy adults the mean x distribution is u=7.4 A random sample of 31 patients for 3 months. Blood test shower x=8.4 with sample standard deviation s= 2.7 Use a 5% level of significance the mean ph level of blood. A) what is the level of significance?__ B)what is the value of the sample test statistics? ( round your answer to three decimal places) ___ 3) 46 adults coyotes average age to be x = 2.07 years with sample standard deviation s= 0.88 years. The population mean age of coyotes is u= 1.75 Minnesota tend to live longer than average 1.75 years?
