Answer:
H0 : μ = 12.50
H1 : μ > 12.50
T - test
Step-by-step explanation:
Given that:
Average, μ = 12.50
Null hypothesis, H0 ;
H0 : μ = 12.50
Alternative hypothesis, H1:
Haveing a greater score on emotion recognition scale;
H1 : μ > 12.50
This is a right tailed test because the equality sign in the alternative hypothesis statement is greater than (Hence to the right).
The hypothesis will be evaluated using a t-test; when sample size is small, usually lesser Than 30
Sample size, n = 25
n < 30 (use t - test)
Answer:
1 + x meters.
Step-by-step explanation:
A square has 4 equal sides so each side will have a length equal to the square root of the area.
Side length = √(1 + 2x + x^2)
= √(1 + x)(1 + x)
= 1 + x.
