- Professor Smith took a sample of 210 students from her morning class and a sample of 163 students from her evening class. On Exam 1, all those sampled from the morning class got a 67 while those sampled from the evening class averaged a 67 with a variance of 127. If Professor Smith combines these two samples.What is the combined Exam 1 Average?What is the combined Exam 1 median?What is the combined Exam 1 Standard Deviation?The amount of chlorine in 100 cm3 water taken from a water tank was measured, the average was 2.15 mg was found. The expert claims that the amount of chlorine in the water is greater than that measured. For this reason, 100 households were randomly selected, with an average chlorine content of 2.55mg and a variance of 0.49 mg. According to this data, find the account value z.a sample of 9 days over the past six months showed that a dentist treated the following numbers of patients: 22, 25, 20, 18, 15, 22, 24, 19, and 26. if the number of patientsseen per day is normally distributed, would an analysis of these sample data reject thehypothesis that the variance in the number of patients seen per day is equal to 10? use a.10 level of significance. what is your conclusion?
- AUA wants to determine whether the mean cumulative GPA, CGPA is significantly different among undergraduate and graduate students (Sheet 31). They collect data on several undergraduate and graduate students. What can they conclude at alpha=0.05? Select one: a. t(stat)=2.56, which is greater than t(cr)=1.68, therefore, we can conclude that there is significant difference in mean CGPAs b. Assuming unequal variances, t(stat)=2.56, which is greater than t(cr)=2.02, therefore, we can conclude that there is significant difference in mean CGPAs c. t(stat)=1.15, which is less than t(cr)=2.12, therefore, we can conclude that there is no significant difference in mean CGPAs d. Assuming equal variances, t(stat)=2.56, which is greater than t(cr)=2.02, therefore, we can conclude that there is significant difference in mean CGPAsSuppose samples are taken from a population of heifers with known mean and standard deviation of weight gains of 186,30 lbs. and 49,19 lbs., respectively.
