Answer:
Area of the counter top is .
Step-by-step explanation:
Given:
Length of the Counter top = 18 feet
Width of the counter top = 3 feet
We need to find the area of the counter top is square meter;
Solution:
Now we need to find the area of the counter top is square meter.
But given data is in feet so we will first convert feet into meters.
1 foot = 0.305 meter.
So 18 feet = Number of meters in 18 feet.
By Using Unitary method we get;
Number of meters in 18 feet =
Length of the Counter top = 5.49 m
Also 3 feet = Number of meters in 3 feet.
Again Using Unitary method we get;
Number of meters in 3 feet =
Width of the counter top = 0.915 m
Now we know that;
Area of the counter top can be calculated by multiplying Length of the counter top with width of the counter top.
framing in equation form we get;
Area of the counter top =
Rounding up to 2 decimals we get;
Area of the counter top =
Hence Area of the counter top is .
Answer:
There is enough evidence to say that the true average heat output of persons with the syndrmoe differs from the true average heat output of non-sufferers.
Step-by-step explanation:
We have to perform a hypothesis test on the difference between means.
The null and alternative hypothesis are:
μ1: mean heat output for subjects with the syndrome.
μ2: mean heat output for non-sufferers.
We will use a significance level of 0.05.
The difference between sample means is:
The standard error is
The t-statistic is
The degrees of freedom are
The critical value for a left tailed test at a significance level of 0.05 and 16 degrees of freedom is t=-1.746.
The t-statistic is below the critical value, so it lies in the rejection region.
The null hypothesis is rejected.
There is enough evidence to say that the true average heat output of persons with the syndrmoe differs from the true average heat output of non-sufferers.
