Question

I already have part a solved.
on part b, I'm kinda doubting myself.
I know that the hypothesis is this, I am just unsure if H1 is greater than or less than, I would imagine it's less than since it says "significantly underweight":

Ho: Mew = 22.7

H1: Mew < or > 22.7

2. A researcher knows that the weights of 6-year olds are normally distributed with a mean of 22.7 kg and
o = 2.8 kg. She suspects that children in poverty-stricken regions are undernourished and therefore
underweight. With a sample of N = 16 children, the researcher obtains a sample mean of X = 20.9
kg.
%3D
(a) Compute a 95% confidence interval for u, the population mean weight for children in poverty-
stricken regions.
(b) Perform a hypothesis test to decide whether children in poverty-stricken regions are significantly
underweight.
