the long sides of a rectangle are 5 ft 6 in and it's perimeter 16 ft 10 in how long are the shorter sides?

1 answer:

5 0

So a rectangle has 2 Long side so that would be a total of 10 ft 12 in which is 13 feet so you
take 16 ft 10 in subtract 13 feet and you get 3 ft 10 in remaining so then you divide that into two because there’s two shorter size and that gives you 1 foot and 11 inches each

Before changes to its management staff, an automobile assembly line operation had a scheduled mean completion time of minutes. T

Sergio [31]

No, we don't have evidence to support that the mean completion time under new management has decreased but we can conclude that it remains at 15.5 minutes.

Given mean of 15.5 minutes , standard deviation of 1.7 minutes, sample size of 90 and sample mean of 15.4 minutes.

We can do the following study for conclusion:

Firstly the null hypothesis is

$H_{0}: x=15.5$

The alternate hypothesis is

$H_{1}: x < 15.5$

since the value is less than this is a one tailed test.

Z=x bar-x/d/ $\sqrt{n}$

where x is sample mean and d is standard deviation.

Z=15.4-15.5/1.7/ $\sqrt{90}$

=-0.1/1.7/9.4868

=-0.560

Critical value of Z at 0.1 level of significance

Z=-1.28

We fails to reject the null hypothesis since -0.560>-1,28

Hence we don't have evidence to support that the mean completion time under new management has decreased but we can conclude that it remains at 15.5 minutes.
