Substitute
, so that

Then the resulting ODE in
is separable, with

On the left, we can split into partial fractions:

Integrating both sides gives




Now solve for

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

And the data given from the sample is:
represent the sample mean
represent the population deviation
represent the sample size
And the statistic would be given by:

Answer:
It is 0.4524 rounded simply you can say 0.45
Step-by-step explanation:
if you multiply 2/7 by 6 which is 12/42 and 1/6 times 7 which is 7/42 and add both fractions you will get 19/42 which is 0.45 you can either say the answer is 0.45 or 19/42.
