Answer:
wouldnt it be 2.05
Step-by-step explanation:
The confidence interval would be (10.44, 12.16). This means that if we take repeated samples, the true mean lies in 90% of these intervals.
To find the confidence interval, we use:

We first find the z-value associated with this. To do this:
Convert 90% to a decimal: 90% = 90/100 = 0.9
Subtract from 1: 1-0.9 = 0.1
Divide by 2: 0.1/2 = 0.05
Subtract from 1: 1-0.05 = 0.95
Using a z-table (http://www.z-table.com) we see that this is directly between two z-scores, 1.64 and 1.65; we will use 1.645:

Answer:
<h3>For ANOVA, the test statistic is called an <u>F-statistic</u> test statistic (also called a <u>F-statistic </u>-ratio), which is the variance (2) samples (a.k.a., variation due to treatment) divided by the variance (3) samples (a.k.a., variation due to error or chance).</h3>
Step-by-step explanation:
- For Analysis of Variance the F-statistic is the Variation between Means of Sample or Variation within the Samples
- For F-tests the F-statistic is the test statistic .
- Generally, an F-statistic is also called as a ratio of two quantities between (here the variance (2) samples (a.k.a., variation due to treatment) divided by the variance (3) samples (a.k.a., variation due to error or chance)). which results an F-statistic of approx 1.

Answer:
Length of the escalator is 33.94 feet.
Step-by-step explanation:
In the attached figure we can see that

It is given that
angle = 45
Vertical Height 'V' = 24 feet
Applying values in the above equation we get
