In a study of a weight lost program , 40 subjects lost a mean of 3.0 lbs after 12 months .. does the weight loss program have statistical significance

Yes, the weight loss program is statistically significant.

Step-by-step explanation:

In a study of a weight lost program , 40 subjects lost a mean of 3.0 lbs after 12 months.

A statistical significance shows if the difference observed between groups is real or if it has occurred simply due to chance. Moreover in statistics, nothing happens by chance.

So, here the weight loss program is statistically significant as the results are unlikely to occur by chance.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

4

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.

you get two and your friend gets four.
