The mean number of steps that Diego walked during the first 4 days of the week is 8,019.If the mean number of steps Diego walks during the last 3 days of the week is 12, 642, will Diego reach his goal of walking more than 70,000 steps this week? Explain your reasoning.

Solution

Diego goal was walk more than 70000 steoes

And in average in the first 4 days he walks 8019 steps

The expected mean number of steps for the next 3 days is 12642 then we can do this:

8019*4 + 12642*3= 32076 +37926 = 70002

then since 70002 > 70000

We can conclude that Diego can reach the goal for this case
