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.
A midpoint divides a line segment into equal halves.
The value of x is 3.4
Given that:
Since M is the midpoint, then:
So, we have:
Collect like terms
Solve for x
<em>Hence, the value of x is 3.4</em>
