Answer:
Parameter = 0.5
Null hypothesis : H0 : P0 = 0.5
Alternative hypothesis ; H0 : P0 > 0.5
Pvalue = 0.99966
Step-by-step explanation:
The parameter defines a statistical value or calculation which is derived from the population.
The parameter in this scenario is the population proportion, P0 which is 0.5
The scenario above describes a scenario to test the difference in population.
The null hypothesis, that bride and groom are of the same age ;
H0 : P0 = 0.5
The alternative hypothesis ; the bride is younger Than the groom in more than half of the population.
H1 : p0 > 0.5
To obtain the Pvalue :
Test statistic : (phat - P0) ÷ √(p0(1 -p0) / n)
Phat = x/n
x = 67 ; sample size, n = 100
Phat = x / n = 67/100 = 0.67
P0 = 1 - 0.5 = 0.5
Tstatistic = (0.67-0.50) ÷ √(0.5(0.5) / 100)
Tstatiatic = 0.17 ÷ 0.05
Tstatistic = 3.4
P-value : p(Z < 3.4) = 0.99966 (Z probability calculator).
Answer:
13/14
Step-by-step explanation:
Area of a rectangle = l * b
=> 4 1/3 = 3 1/2 + b
=> (4 1/3) / (3 1/2) = b
=> (13/4) / 7/2 = b
=> 13/4 * 2/7
=> 13/2 * 1/7
=> 13/14
Therefore the width = 13/14

Answer:
B
Step-by-step explanation:
eliminating systematic measurement errors caused by errors in the measuring instrument used to compare the quantity being measured with a standard.
The elimination method is the process of solving the system of equations, by cancelling unknowns in the system. This makes more simple to solve and easy to solve for the resting unknowns.
Equation solving. A solution is an assignment of expressions to the unknown variables that makes the equality in the equation true. In other words, a solution is an expression or a collection of expressions (one for each unknown) such that, when substituted for the unknowns, the equation becomes an identity .
