Question
Two of the hottest smartphones on the market are the newly released iPhone6 and the Samsung Galaxy S6. CNet.com offers online reviews of all major cell phones, including battery life tests. In a review of the iPhone6, the talk-time battery life of 35 iPhones was measured. Similarly, the talk-time battery life of 30 Galaxy S6s was measured.
Two outputs are given below. Which is appropriate for analyzing the data collected?
- Output 1
- Output 2
Using the StatCrunch output chosen above, determine if there is a difference in the mean battery life for the two phones. Use a significance level of 0.01 when conducting the test.
- Select the appropriate hypotheses. Make sure the notation used in the hypotheses agrees with the type of samples selected in the output.

- probability = (make sure you reference the probabilities in the output you selected in the first question)
- decision: Select an answer fail to reject H₀ reject H₀
- At the 0.01 level, there Select an answer is not is significant evidence to conclude the mean battery life for an iPhone 6 is Select an answer greater than different than less than than the mean for a Galaxy S6.
