Answer:

92

Step-by-step explanation:

nth term = a₁ + (n - 1)d

19th term = 2 + (19 - 1) * 5

               = 2 + 18*5

               = 2 + 90

               = 92

In a small town, 50% of single family homes have a front porch. 48 single family homes are randomly selected. Let X represent th
Reil [10]

Answer:

N(24, 3.46)

Step-by-step explanation:

We are given the following in the question:

Percentage of family homes having front poach = 50%

p = 50\% = 0.50

Sample size, n = 48

Normal approximation to the given distribution:

\mu = np = 48(0.50) = 24

\sigma = \sqrt{np(1-p)} = \sqrt{48(0.50)(1-0.50)} = 3.46

Thus, the distribution of single family homes is best approximated by the normal distribution N(24, 3.46) where mean is 24 and standard deviation is 3.46
