Answer:
Step-by-step explanation:
The formula for determining confidence interval is expressed as
Confidence interval
= mean ± z × s/ √n
Where
z is the value of the z score
s = standard deviation
n = sample size
a) The 95% confidence level has a z value of 1.96
The 99% confidence level has a z value of 2.58
Since 99% confidence level z value is greater than 95% confidence level z value, if we input it into the formula, it will result to a higher confidence interval. So changing from a 95% confidence level to a 99% confidence level would make a confidence interval wider.
b) The √15 is smaller than the √350. This means that if we make use of the formula, √350 will give a lower confidence interval than that of √15. Therefore, the confidence interval would be narrower changing from a sample size of 15 to a sample size of 350.
c) Applying the formula, a standard deviation of 15 pounds would result to a lower confidence interval than a standard deviation of 20 pounds. Therefore, the confidence interval would be wider changing from a standard deviation of 15 pounds to a standard deviation of 20 pounds.
There is a horizontal asymptote at y = 0 so the range is y < 0
The headings correctly complete the chart is X: Zygote fungi
, Y: Club fungi
, and Z: Sac fungi.
Option: D.
<u>Explanation:</u>
Zygote fungi
: Zygote fungi are terrestrial and exist in decaying plants, animal material or soil. It reproduces asexually through sporangia(spore-producing enclosure) hyphae, which will be loosely organized or assorted into complex structures.
Club fungi
: Club fungi can be found in the form of puffballs, mushrooms, and rusts. The spores are produced by sexual reproduction and the spores drip from its "gills" which is firmly packed hyphae.
Sac fungi: Sac fungi exist in freshwater, marine, and terrestrial environments. They are single-celled kinds that usually reproduce asexually during suitable conditions, and sexually during the harsh conditions.

Step-by-step explanation:
Absolute value means whatever is inside of it is always positive so 15 is greater than -12.
