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

$H_0: \bar x = 325\\H_a: \bar x$

(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.

Yesterday, Jack drove 33 and one half

borishaifa [10]

change each mixed number to an improper fraction

33 1/2 = (2*33 +1)/2 67/2

1 1/4 = (4*1+1)/4 = 5/4

67/2 divided by 5/4

copy dot flip

67/2 * 4/5

268/10

26 8/10

26 4/5 miles per gallon
