Answer:
(0,5)
x,y
Step-by-step explanation:
From the given data, the value of N is equal to 5, The value of X is equal to 2. Since 38% of the consumers are comfortable with drone, this makes the value of P equal to 0.38. And now using the equation to find Q = 1 - P, where P is 0.38, we now get 1 - 0.38, therefore Q = 0.62. To summarize, N =5; X = 2; P = 0.38; Q = 0.62
Answer:
0.09
Step-by-step explanation:
Let x = ages of mother
x : 22 17 27 20 23 19 24 18 19 24
N = 10
Mean = ∑x/N = 218/10 = 21.8
Difference in mean = 21.8 - 20 = 1.8
If significance level = 5% or 0.05
∴ Rejection region = 1.8 X 0.05 = 0.09
