Greg built a plane model. The initial weight of Greg's model was 21.8 pounds. He added a propeller that weighed of the initial weight of the model. Greg estimates that the total
weight of the model with the propeller is about 24 pounds. Is Greg's estimate of the total
weight of the model reasonable?
Greg built another model. The initial weight of this model was 22.7 pounds. He added wings
that weighed of the initial weight of the model. Greg estimates that the total weight of the
model with the wings is about 27 pounds. Is Greg's estimate of the total weight of the model
reasonable?

It appears that people who are mildly obese are less active than leaner people. one study looked at the average number of minutes per day that people spend standing or walking. among mildly obese people, the mean number of minutes of daily activity (standing or walking) is approximately normally distributed with mean 376 minutes and standard deviation 64 minutes. the mean number of minutes of daily activity for lean people is approximately normally distributed with mean 528 minutes and standard deviation 107 minutes. a researcher records the minutes of activity for an srs of 7 mildly obese people and an srs of 7 lean people. use z-scores rounded to two decimal places to answer the following: what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 mildly obese people exceeds 420 minutes? what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 lean people exceeds 420 minutes?
