Hello there, and thank you for posting your question here on brainly.
To convert a decimal to a percent, you have to make the decimal a whole number by getting rid of the decimal point, and then at a % sign.
0.125 ===> 125
125 ===> 125%
Hope this helped!! ☺♥
Answer: Alternative Hypothesis
Ha : u ≠ 80 inches ( mean not equal to 80 inches)
Step-by-step explanation:
The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean.
While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.
For the case above, the mean door height is 80 inches
H0 : u = 80 inches
Ha : u ≠ 80 inches ( mean not equal to 80 inches)
Answer:
a. a parameter.
Step-by-step explanation:
A parameter is a property that describes the whole population, while a statistic is a property pertaining to a sample or sub-set of the population.
In this example, the average content of 4 ounces pertains to the 121 bottles sample and thus is a statistic. While the standard deviation of the population is mentioned to be 0.22 ounces, therefore 0.22 is a parameter.
Well, since it only asking about the product, you don't have to multiply the result
The product would be :
3 x 2 = 6
3x 20 = 3 x 2 x 10 = 60
3 x 200 = 3 x 2 x 10 x 10 = 600
hope this helps
I don’t really understand this question so I will try to figure it out later
