Atelevision network commissioned a telephone poll of randomly sampled men. of the 708 respondents who had children, 19% said "yes" to the question "are you a stay-at-home dad? " to market commercial time, the network wants an accurate estimate of the true percentage of stay-at-home dads. construct a 90% confidence interval. left parenthesis nothing % comma nothing % right parenthesis

(16.6%, 21.4%)

Step-by-step explanation:

The confidence interval for proportion is given by :-

Given : Sample size : n= 708

The proportion of respondents who had children =

Significance level :

Critical value :

Now, the 90% confidence interval for proportion will be :-

Hence, the 90% confidence interval for the proportion = (16.6%, 21.4%)

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

she would want to sell 10 full-year subscriptions and at least 9 half-year subscriptions to get a total of at least $300.
