Previously 5% of mothers smoked more than 21 cigarettes during their pregnancy. An obstetrician believes that the percentage of

Answer:

p value = 0.03514

Step-by-step explanation:

Hypotheses would be

$H_0: p = 0.05\\H_a: p$

(left tailed test at 10% level of significance)

Here p stands for the sample proportion of mothers smoked more than 21 cigarettes during their pregnancy.

Sample size =130

persons who smoked = 2

Sample proportion = $\frac{2}{130} \\=0.0154$

Assuming H0 to be true

Std error= $\sqrt{0.05*0.95/130} \\=0.01911$

p difference = -0.0346

Test statistic z=-1.81

p value = 0.03514

Since p is less than 0.10, significance level, we reject H0

Please help, thanks.

Liula [17]

Answer:

$\frac{ - 5}{54} + \frac{5 \times 6}{9 \times 6} = \frac{ - 5 + 30}{54} = \frac{25}{54}$

$\frac{15}{4} \div \frac{3}{8} = \frac{15}{4} \times \frac{8}{3} = 10$

$10 \times \frac{25}{54} = \frac{250}{54} = 4 \times \frac{17}{27}$

b )

$4 \times \frac{17}{27} = \frac{125}{27} =$

cube root =

$\frac{5}{3}$

c ) square root

$\frac{125}{27} = \frac{ \sqrt{25 \times 5} }{ \sqrt{3 \times 9} } = \frac{5 \sqrt{5} }{3 \sqrt{3} }$

Digiron [165]

Answer:

associative

combining

commutative

Step-by-step explanation:

1. <em>associative property of addition</em> since the grouping is changed

2. <em>combining like terms</em> since it's the addition of 4 and 6

3. <em>commutative property of addition</em> since it's a change of order
