Answer:
Given:
Sample size, n = 120
P = 48% = 0.48
p' = = 0.4
Significance level = 0.10
Null and alternative hypotheses are:
H0 : P = 0.48
H1 : P ≠ 0.48
For the test statistics:
Z = -1.754
P-value: This is a two tailed test.
For Z = -1.754 the P-value = 0.7943
Critical value: a = 0.10, 2 tailed test, Z critical = +1.645, -1.645
Decision Rule: We reject H0, if pvalue is less than significance level. We also reject H0 is Z observed is greater than Z critical.
Decision: Since pvalue, 0.7943 is greater than significance level, 0.10 we fail to reject null hypothesis, H0.
Conclusion:
There is not enough sufficient evidence to conclude that percentage of people who believe there is life on other planets differs from 48%
Answer: 1
x(3−2)(2−5)=3
Step 1: Simplify both sides of the equation.
−3x=3
Step 2: Divide both sides by -3.
x=1
