Hello!
The parameter of interest is "the population proportion of people that like soccer A news channel"= p
The hypothesis are:
H₀: p = 0.45
H₁: p ≠ 0.45
To study the population proportion you have to use the approximation of the standard normal distribution:
≈ N(0;1)
A sample of n=30 was taken and surveyed, 18 of those answered positively, then the sample proportion is:
p'= 18/30= 0.6
The statistic under the null hypothesis is:
I hope it helps!
Answer:
B, C, E
Step-by-step explanation:
the dependent variable <em>depends </em>on the independent variable
thus, p is dependent on t, p is the dependent variable, and t is the independent variable (B)
every month, Gloria paints 2 pieces
each month, t is increased by 1, and p is increased by 2 (C)
every month, Gloria paints 2 pieces
2 pieces every month = (2*t) pieces = total pieces = p (E)
√(4) is equal to 4 raised to the (1/2). 1/2 as an exponent is between 0 and 1 and it means to take the square root.
So, 4^(1/2) = 2 (or -2)
