# Important information about Two Sample T test for testing the Hypothesis of Means

n = 17

M = 34.4

s = 4.0

n = 19

M = 31.9

s = 3.5

Use a single sample t test to determine whether sample 1 is significantly above the average of 30/kg/m2.

One tailed test with a = .01

Also,

What does this mean in words:

t(18) = 4.00, p = .001, d = 1.79

When you have s (M1 - M2), does that mean the s gets multiplied by (M1 - M2)?

#### Solution Preview

The solution is very helpful to understand the concept of these types of problem. Step by step solution is attached for better understanding and clarity to this problem.

n = 17

M = 34.4

s = 4.0

Use a single sample t test to determine whether sample 1 is significantly above the average of 30/kg/m2. one tailed test with a = .01

For First Sample:

Solution:

Null Hypothesis (Ho): µ = 30

Alternative Hypothesis (Ha): µ > 30 (One tailed test)

Level of Significance (α) = .01

The critical value of t distribution at .01 with n-1 = 17-1=16 degree of freedom is given as 2.583

Test statistics is given by

The test statistic is a t-score (t) defined by the following equation.

t = (M - μ) / SE

Where M is the sample mean, μ is the hypothesized ...
