Answer:

true

Explanation:

stars can change bc Stars change over time. ... It is in the clouds of dust and gas that stars are born. As more and more of the gas (which is mostly hydrogen) is pulled together by gravity into a cloud, the cloud starts to spin. The gas atoms start to bump into each other faster and faster.

andrey2020 [161]

Answer:

Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are perhaps the most important molecules in cell biology, responsible for the storage and reading of genetic information that underpins all life. They are both linear polymers, consisting of sugars, phosphates and bases, but there are some key differences which separate the two1. These distinctions enable the two molecules to work together and fulfil their essential roles. Here, we look at 5 key differences between DNA and RNA. Before we delve into the differences, we take a look at these two nucleic acids side-by-side.

What is the 95% CI for data set 2?
vesna_86 [32]

Answer: 20 ± 11.32

Explanation: <u>Confidence</u> <u>Interval</u> (CI) is an interval of values where there is a % certainty the true mean value lies in. For example, a 95% CI means there is a 95% certainty the true mean value lies in the interval.

For the data set 2, z-value for 95% confidence interval is z = 1.96

Formula to calculate CI is

x ± z\frac{s}{\sqrt{n} }

where

x is mean

z is z-value

s is standard deviation

n is the sample number

Then:

20 ± 1.96\frac{10}{\sqrt{3} }

20 ± 1.96\frac{10}{1.7320}

20 ± \frac{19.6}{1.7320}

20 ± 11.32

The 95% CI is 20 ± 11.32, which means there is a 95% certainty the true value is between 8.68 and 31.32.
