The rivercondos files has a random sample of data from two different kinds of condos. one kind of condo has a river view (river_list price, river_sales price, river_days to sell, and river_pmi) and the second kind does not have a river view (noriver_list price, noriver_sales price, noriver_days to sell, and noriver_pmi). these variables describe the list price the last time a condo was put up for sale, the final sales prices, how many days it took the unit to sell, and whether or not the sale involved principal mortgage insurance (pmi). list prices and sales prices are given in thousands of dollars.
for the variable river_pmi, why can you conclude that the sampling distribution of the sample parameter is normally distributed?
a. because n p = 19 np=19 and n ( 1 − p ) = 13 n(1-p)=13
b. because n = 30 ≥ 30 n=30≥30
c. because n = 40 > 30 n=40> 30
d. because n p = 19 np=19 and n ( 1 − p ) = 21 n(1-p)=21
e. none of the above

Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.
