The birth weights of 34 babies whose mothers did not smoke and 29 babies whose mothers smoked were compared; weights were in grams. test the hypothesis that the population mean birth weight is larger for mothers who do not smoke. assume that the sample is random and the distributions are normal, and use a significance level of 0.05. a. explain why this data set is not paired. b. which sample mean is larger, and how do you know? c. test the hypothesis that the population mean birth weight is larger for mothers who do not smoke.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
