True/False from Activity 14 Interpretations: Suppose a random sample of 114 students was chosen, and each student was asked how many hours he or she studies each week. The resulting 95% confidence interval for  was (8.9, 11.8). Determine if each one of the following statements is true with a capital “T” or false with a capital “F.” __F_ a) 95% of all students study between 8.9 and 11.8 hours per week. __F_ b) 95% of all sample means will be between 8.9 and 11.8. __F_ c) 95% of samples will have averages between 8.9 and 11.8. __F_ d) For 95% of all samples,  will be between 8.9 and 11.8. __T_ e) For 95% of all samples,  will be included in the resulting 95% confidence interval. __F_ f) The formula produces intervals that capture the sample mean for 95% of all samples. __T_ g) The formula produces intervals that capture the population mean for 95% of all samples.
