Sample size and power.

Davis and Loprinzi (2016) evaluated a hypothesis related to engaging children, adolescents, and adults in physical activity. As part of their study, they reported a sample size of 106 children, 128 adolescents, and 440 adults.

Assuming equal effect sizes across these age groups, which age group is likely to be associated with greater power to detect effects of physical activity? Explain.

the picture is the step by step explanation.

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
