Given:
An elevation of - 12 m is higher than an elevation of -17 m.
An elevation of - 17 m is lower than an elevation of -14 m.
To find:
The set of inequalities that correctly expresses these relationships.
Solution:
An elevation of - 12 m is higher than an elevation of -17 m.
We know that, higher than means greater than and it is represented by the inequality ">". So,
An elevation of - 17 m is lower than an elevation of -14 m.
We know that, lower than means less than and it is represented by the inequality "<". So,
Therefore, the required set of inequalities is and
.
Note: The inequality signs are not proper in the options.
Answer:
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.
