Answer:
0.9938
Step-by-step explanation:
Let mean blood pressure be = x
Pr ( x < 119 ) can be found using ' z value ' = ( x - u ) ÷ ( s / √n ) ; where x = 119 , u = mean = 117 , n = no. of sample items = 144 , s = standard deviation = 9.6
z = (119 - 117) ÷ (9.6 / 144) = -2 ÷ (9.6 / 12) = -2 / 0.8 → z = 2.5
Pr (x < 119) = P (z < 2.5)
P = 0.9938
Answer:
-6 + 12x
