Andre plans to hike the same mountain trail one more day. Estimate the time it will take him to complete the trail for the seventh day. Explain your reasoning.
What do you think will happen to the mean time for the week if Andre's grandfather comes on the hike with him for the seventh day?
Andre and his grandfather hiked the mountain in 130 minutes. Calculate the mean hiking time for all seven days: 50, 52, 58, 55, 59, 50, 130.
If Andre’s grandfather did not come with him on the hike, Andre thinks he could have finished the trail in 60 minutes. Calculate the mean hiking time for all seven days using Andre’s estimate for the seventh day: 50, 52, 58, 55, 59, 50, 60.
