Let x be the number then
"the product of 7 and a number"
"Six subtracted from the product of 7 and a number"
"is greater than -19"
Hence, the given scenario in mathematical form is:

Answer:
We define the random variable X as the walking age and we are interested if American children learn to walk less than 15 months so then that would be the alternative hypothesis and the complement would be the null hypothesis.
Null hypothesis:
Alternative hypothesis:
And for this case the best answer would be:
H 0 : μ ≥ 15 vs. Ha : μ < 15
