Solve egch problem by writing and solving an equation,
seki and raina sold a total of 152 candles for their school fund-raiser. if seki sold three boxes of candles and
raina sold two boxes plus twelve single candles, how many candles come in each box?
(
3-25 + 12 = 162, b = 150
3 - 2 + 12 = 162,6 =30
they
3*20-12- 162, b = 35
3+2+12= 162,5=35

A. find the power of the test, when the null hypothesis assumes a population mean of mu = 450, with a population standard deviation of 156, the sample size is 5 and the true mean is 638.47 with confidence intervals of 95 b. find the power of the test, when the null hypothesis assumes a population mean of mu = 644, with a population standard deviation of 174, the sample size is 3 and the true mean is 744.04 with confidence intervals of 95% c. find the power of the test, when the null hypothesis assumes a population mean of mu = 510, with a population standard deviation of 126, the sample size is 10 and the true mean is 529.44 with confidence intervals of 95
