An experiment was conducted to investigate whether there is a difference in mean bag strengths for two different brands of paper

Elanso [62]

Answer:

A two-sample t-test for a difference between sample means

Step-by-step explanation:

Explanation:-

A random sample of 50 bags from each of Brand X and Brand Y was selected

Given two sample sizes n₁ and n₂

Each bag was held from its rim, and one-ounce weights were dropped into the bag one at a time from the same height until the bag ripped

mean of ounces the first sample = x⁻

mean of the second sample =y⁻

Given data one-ounce weights were dropped into the bag one at a time from the same height until the bag ripped

Standard deviation of the first sample = S₁

Standard deviation of the second sample = S₂

Now we use t - distribution for a difference between the means

$t = \frac{x^{-} -y^{-} }{\sqrt{S^{2}(\frac{1}{n_{1} } +\frac{1}{n_{2} } } }$

where

$S^{2} = \frac{n_{1} S_{1} ^{2} +n_{2}S_{2} ^{2} }{n_{1} +n_{2} -2 }$

Degrees of freedom γ = n₁ +n₂ -2
