Short Answer

In planning a study of the birth weights of babies whose mothers did not see a
doctor before delivery, a researcher states the hypotheses as
$\begin{matrix} H_{0} : μ < 1000 grams \\ H_{a} : μ = 900 grams \end{matrix}$

The problem is incorrect as the population mean value is $1000$ as per the null hypothesis and is less than $900$ as per the alternative hypothesis.

Step 1: introduction

Given,

In planning a study of the birth weights of babies whose mothers did not see a

doctor before delivery, a researcher states the hypotheses as

$\begin{aligned} H_{0} : μ < 1000 grams \\ H_{a} : μ = 900 grams \end{aligned}$

Step 2: explanation

Calculating the hypothesis,

population mean value is $1000$ as per the null hypothesis

role="math" localid="1651657895247" $\Rightarrow H_{0} : μ = 1000$

population mean value is less than $900$ as per the alternative hypothesis

role="math" localid="1651657899211" $\Rightarrow H_{a} : μ < 900$

The problem is incorrect as the population mean value is $1000$ as per the null hypothesis and is less than $900$ as per the alternative hypothesis.
