If the alternative hypothesis of an experiment is "The true mean height of children is less than 60 inches," what is the null hypothesis?

if correct will give brainliest!

Null Hypothesis : The true mean height of children is more than 60 inches.

Step-by-step explanation: Null Hypothesis is defined as a hypothesis that there is no significant difference between the observed and sampled mean.

So, if alternative hypothesis is " the true mean height of children is less than 60 inches" which denotes there is significant difference between sampled and observed mean heights so null hypothesis is taken as " true mean height of children is more than 60 inches"
