Convert 150 base 10 to a binary <br>number.
STALIN [3.7K]

Answer:

10010110

Step-by-step explanation:

A binary number is basically a number in base 2. So, each place represents a power of two. The ones place represents 1 or 2^0, the tens represents 2 or 2^1, the hundreds represents 4 or 2^2 and so on. To find the highest place needed to make in the number in binary, we find the greatest power of two that is below 150. In this case, it is 128. We can start by writing 128 in binary:

10000000

Now, we subtract 128 from 150 and find the largest power of two that is smaller than the difference. The largest power of 2 smaller than 22 is 16, so we put a one in the place for 2^4:

10010000

We can subtract 16 from 22 to get what is leftover to continue the process. We get 6, and the largest power of 2 smaller is 4. We can place a one in the hundreds place to represent it:

10010100

What is left is 6-4 or 2, which is just 2^1, so we can place it in the tens place:

10010110

Use StatKey or other technology to generate a bootstrap distribution of sample proportions and find the standard error for that
sesenic [268]

Answer:

0.0515

Step-by-step explanation:

By the central limit theorem

when n increase distribution when data follows normal

Standard Error, SE of P is

SE = \sqrt{\frac{p(1-p)}{n} }

Bootstrap Standard Error = \sqrt{\frac{p(1-p)}{n} }

where n = 94 and p = 0.52

hence,

SE of Bootstrap = \sqrt{\frac{0.52(1-0.52)}{94} }

=\sqrt{\frac{0.2496}{94} }\\\\=0.0515

SE and the SE of Bootstrap are the same
