Answer:
200
Step-by-step explanation:
75%; so if we say there are 100 people in this city that means 60 of them live in houses and 40 of them live in apartments. Of the 60 living in houses 20% of them (12% of total population; 60 x .20) own their own business and those in apartments (40) 10% of them (4% of total pop.; 40 x .10) have their own business. In total 16 of the 100 people have businesses and 12 of those people live in houses so 12/16 equals .75. We multiply this by 100 to get the percent so there’s 75% that a person who owns a business in this city will also live in a house.
Answer:
65

Answer:
z = -0.57
Step-by-step explanation:
A z-score indicates how much away is something from the mean so it can be more(above) than the mean or less(below) than the mean.
sampling distribution mean = 0.03
standard error = 0.007
researcher's sample mean = 0.026
z = (0.026 - 0.03)/0.007
z = (-0.004)/0.007
z = -0.57
So that means the researcher's sample mean is 0.57 standard deviation below the sampling distribution mean.
The negative sign above is the indicator of below the mean value.
