The given ratio for the measure of a pair of corresponding sides of similar polygon is also the same for all the sides. The perimeter, which is the sum of the measures of all the sides, will also have the same ratio. Thus, for the given above, the answer would be the third choice, 3/9 = 1/3.
Answer:
neither normal distribution nor t-distribution
Step-by-step explanation:
given data
no of sample = 15
mean = $105
standard deviation = $30.25
to find out
whether a normal distribution or a t-distribution
solution
this is neither normal distribution nor t- distribution because here we know t, z is use for normal and difference ( n greater than 30 and Standard Deviation used z and the for n less than 30 , Standard Deviation not known use for t distribution ) so it we can say it is neither normal distribution nor t- distribution
