Use the given information to find the number of degrees of freedom, the critical values x and x², and the confidence interval estimate of o. It is reasonable to assume that a simple random sample has been selected from a population with a normal distribution. Platelet Counts of Women 95% confidence; n = 27, s= 65.2. 11 Click the icon to view the table of Chi-Square critical values. df= (Type a whole number.) x² = (Round to three decimal places as needed.) x² = (Round to three decimal places as needed.) The confidence interval estimate of o is (Round to one decimal place as needed.)

Use the given  information  to find the number of degrees  of fr, the critical  values X2L and X2R and the confidence  interval estimate  of the standard  deviation.  It is reasonable  to assume that a simple random  sample  has been selected from a population  with a normal  distribution.  Nicotine  in menthol cigarettes  95% confidence  n= 20, s= 0.27 mg.

A sample mean, sample standard deviation, and sample size are given. Use the one-mean t-test to perform the required hypothesis test about the mean, μ, of the population from which the sample was drawn. Use the critical-value approach. Sample mean = 7.1                 s = 2.3             n = 18              α = 0.01 H0: µ = 10 H1: µ < 10 The critical value(s) is/are (If there are two critical values separate each with a comma and list from smallest to largest)
