Answer:
Following are the answer to this question:
Step-by-step explanation:
Given:
n = 30 is the sample size.
The mean
= 7.3 days.
The standard deviation = 6.2 days.
df = n-1

The importance level is
= 0.10
The table value is calculated with a function excel 2010:

The method for calculating the trust interval of 90 percent for the true population means is:
Formula:


It can rest assured that the true people needs that middle managers are unavailable from 5,37 to 9,23 during the years.
Step-by-step explanation:
okay so we know i = prt
in this scenario
p = 22,000
r = ?
t = 7
i = 27,390
the equation for r is (i/p*t)
so now let's plug in what we know
r = 27,390/22,000 * 7
r = 1.245 / 7
<u><em>r = 8.715</em></u>

Answer:
<u>For one Necklace you would need...</u>
24 blue beads.
16 white beads.
4 green beads.
Ratio: 24: 16: 4
Step-by-step explanation:
If you quadruple the amount of beads from the original amount (6 : 4: 1), the total beads for that necklace will be 44.
Step 1: 6 x 4 = 24 (amount of blue beads in necklace).
Step 2: 4 x 4 = 16 (amount of white beads in necklace).
Step 3: 1 x 4 = 4 (amount of green beads in necklace).
Now check to see if the total of all types of beads sum up to 44:
Step 4: 24 + 16 + 4 = 44
______________-
There is your answer:
You need 24 blue beads, 16 white beads, and 4 green beads to have a total sum of 44 beads in that one necklace.
<span>In statistics finding percentiles relates to the standard deviation and something called a z-score. For normally distributed data the z-score represents how many standard deviations above or below the mean that group is a part of. The z-score for normally distributed data for the 90th percentile is 1.28. The standard deviation is then multiplied by the z-score to find, in this case, the shotlrtest height needed to be in the 90th percentile of this population. In this case to be in the 90th percentile your height must be 60.27 inches.</span>
