Sample size Sample Sample Groups mean variance Normal hearing 15 2.41 0.1 Hearing aid 15 2.01 0.4 Some hearing 15 1.98 0.1 loss Send data to calculator Are there differences in the mean sone values for this tone for the populations of listeners aids, and listeners with low-frequency hearing loss? We can perform a one-way, independe question. Such a test uses the following statistic. Variation between the samples F= Variation vithin the samples For the data summarized above, F 3.81. (a) Give the numerator degrees of freedom of this F statistic. (b) Give the denominator degrees of freedom of this F statistic. (c) Based on these data, and using the 0.01 level of significance, should you cònclude that there are differences in the mean sone values for this tone Yes O No among the three groups?
