The measured residual flame time, in seconds, for strips of treated children’s nightwear are given in the following table. 9.85 9.93 9.75 9.77 9.67 9.87 9.67 9.94 9.85 9.75 9.83 9.92 9.74 9.99 9.88 9.95 9.95 9.92 9.93 9.89 Suppose a true average flame time of at most 9.75 seconds had been mandated. Does the data suggest that this condition has not been met? Carry out an appropriate test after first investigating the plausibility of assumptions that underlie your method of...

The National Retail Federation reported that Halloween spending for 2009 had declined from previous years. According to their polls, the average adult spent approximately $66 on Halloween costumes, candy, decorations, etc. in 2008. However, a sample of n= 30 families in 2009 produced a mean of M = $56 with SS = 11600. Use the steps below to determine whether these data indicate a significant decrease in 2009 holiday spending compared to 2008. a. Which type of hypothesis test is...

In the following research, identify 1. test type, 2. null hypothesis, 3. alternate hypothesis, 4. test statistic, 5. p-value, and 6. conclusion. When engaging in weight-control (fitness/fat burning) types of exercise, a person is expected to attain about 60% of their maximum heart rate. For 20-year-olds, this rate is approximately 120 bpm. A simple random sample of one hundred 20-year-olds was taken, and the sample mean was found to be 107 bpm with a standard deviation of 45 bpm. Researchers...
