Hi,

Could you please help me with this problem:

The batteries should have a target discharge measurement at least 1075mAh. Write null and alternative hypothesis to test if the sample of 30 batteries implies the population of batteries meets the target of 1075mAh or more.

We'll be glad to help! We just need to know what you've tried and where you're stuck. Thank you! ;)
 
Hi,

What I think is:

Ho: μ=> 1075 and Ha: μ<1075

Which is a left tail test.
