T Distribution Means Hypothesis Test

It is a type of inferential statistic used to determine if there is a significant difference between the means of two groups, which may be related in certain features.

• ANOVA

• Chi-Square

• Standard Deviation

• t-test

H₀: μ = k

H₁: μ ≠ k

• Left-tailed test

• Two-tailed test

• Right-tailed test

Identify the t-value whose number of samples n = 9 and has an area (𝛼) equal to 0.05

• 0.261

• 1.833

• 1.860

• 3.355

Claim: The average weight of males is greater than 53 kg. Ten male students were selected to test this claim.We also set our ⍺ = 0.01. \(\alpha=0.01,\ \overline{x}=51,\ s=4.74,\ n=10,\ df=10-1=9\) Using the formula, compute for the test value. Step 3: What is the test value or computed value?

• Failed to reject the null hypothesis 

• Reject the null hypothesis 

For the t-test one uses __________ instead of σ.

• n

• s

• χ²

• t

In the hypothesis testing, the null hypothesis states that all means are all equal (H0 = u1 = u2 = u3)

• True

• False
