In terms of morphology, Homo rudolfensis and <u>Homo habilis </u>can be considered to be one species.

An extinct species of early Pleistocene humans known as Homo habilis, or "handy man," lived in East and South Africa between 2.31 million and 1.65 million years ago. When H. habilis was first described as a species in 1964, there was a lot of debate about it.

Many scientists suggested that it be grouped with Australopithecus africanus, the only other early hominin that was known at the time, but as time went on and more pertinent discoveries were made, Homo habilis gained more recognition. By the 1980s, it was believed that Homo habilis was a direct progenitor of modern humans, developing into Homo erectus along the way.

A manufacturer of potato chips would like to know whether its bag filling machine works correctly at the 426 gram setting. Based
Blababa [14]

The conclusion of the research is that we reject the null hypothesis and we conclude that the bag filling machine does not work correctly at the 426 gram setting.

<h3>How to solve hypothesis testing?</h3>

We are given;

Population Mean; μ = 426

Sample mean; x' = 433

Sample size; n = 13

Standard deviation; s = 29

significance level; α = 0.05

Let us define the hypotheses;

Null Hypothesis; H₀: μ = 426 g

Alternative Hypothesis; H_a: μ < 426 g

Formula for the z-score here is;

z = (x' - μ)/(s/√n)

z = (433 - 426)/(29/√13)

z = 0.87

From online p-value from z-score calculator, we have;

p-value =  0.1922

This p-value is greater than the significance value and as such we reject the null hypothesis and we conclude that the bag filling machine does not work correctly at the 426 gram setting.
