Step-by-step explanation:
Given that a nutrition lab tested 40 hot dogs to see if their mean sodium content was less than the 325-mg upper limit set by regulations for "reduced sodium" franks
90% confidence interval is
(317.2, 326.8)mg.
Using confidence intervals,we can check whether null hypothesis is true.
Here
(left tailed test at 10% significance level)
We check whether confidence interval 90% contains the mean value.
We find 325 belongs to the confidence interval
Hence H0 is true
The hot dogs do not satisfy.
Answer:
38 %
Step-by-step explanation:
1. Percent of lawns mowed
2. Percent of lawns unmowed
% Unmowed = 100 % - 62 % = 38 %
Henry still needs to mow 38 % of the lawns.
