Answers and Step-by-step explanation:
Hypotheses are:
H o=19.8
H 1 ≠19.8
Here we have following information:
s=2.45, X bar=20.1, n=50
So test statistics will be
t=20.1-19.8/(2.45/
=0.87
Degree of freedom : d f = n - 1 = 50 - 1 =49
Test is two tailed so critical value of the test is -1.30 and 1.30.
Rejection region:
if t < -1.30 and t > 1.30, reject H o
Since test statistics lie in the rejection region so we fail to reject the null hypothesis.
(b)
The observed significance of the test is
P value =0.3885
(c)
Since p value is greater than 0.20 so we fail to reject the null hypothesis.
As a teacher, you can set up food donations for the students who live in a food desert. Provide healthy snacks for them to eat.
(3 g/day)/(0.250 g/tablet) = 12 tablet/day
2.45 divided by seven equals .35.
So each oranges is .35¢
So now multiply .35 by 8 and you’ll get a total of $2.80
$2.80 for 8 oranges.
