Answer:
We conclude that cheddar popcorn weighed less than 5.5 ounces.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ =5.5 ounces
Sample mean, = 5.23 ounces
Sample size, n = 64
Alpha, α = 0.05
Sample standard deviation, σ = 0.24 ounce.
First, we design the null and the alternate hypothesis
We use One-tailed z test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
We reject the null hypothesis and accept the alternate hypothesis. Thus, we conclude that cheddar popcorn weighed less than 5.5 ounces.
Answer:

The range of a set of numbers is the difference between the largest number and smallest number. In this case the most hours spent by any given student is 3, and the least is 0.
So the range is 3 - 0 = 3 hours.
<em>Answer:</em>
<em>The cost of the racquet is $135</em>
<em>Step-by-step explanation:</em>
<em>Let</em>
<em>x-----> the cost of the racquet</em>
<em>we know that</em>
<em>The racquet represent the 100%</em>
<em>so</em>
<em>using proportion</em>
<em />
<em>x/100%= $9.45/7%</em>
<em>x=100%*($9.45)/7</em>
<em>x=$135</em>
