A newspaper editor wants to investigate whether the residents of two counties support the proposal to
build a wind farm. She plans to take an SRS of 30 residents from the southern county and 40 residents
from the northern county, then look at the difference (southern - northern) between the proportions
of residents that support the proposal in each sample. Suppose that 65% of the residents of the southern
county and 52% of the residents of the northern county approve.
What are the mean and standard deviation of the sampling distribution of the difference in sample

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.
