3 0

Answer:

Since we have the normally distributed data set of the 500 observations. hence, according to the formula there will be 95% of the total observation within two standard deviations from the mean.

Hence, no. of observations will be= 95% of 500= 95 *5 = 475

Also remember standard deviation is (Xi-X')²

The standard deviation is the measurement of the dispersion of the data set from the mean. And its quite important in Data science.

Explanation:

The answer is self explanatory.

oksian1 [2.3K]

Answer:

Following are the answer to this question:

Explanation:

A)

The memory size is 1 Giga Bytes which is equal to 2^{30}

\texttt{Number of address bits    \ \ \ \ \ \ \ \ \ \ \ \ \ \            Number of addresses}\\\\ \ \ \ \ 30  \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \  \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \                                 2^{30}= 1073741824

B) \texttt{I \ \ \ Opcode  \ \ \ Register address \ \ \  Immediate operand \ \ \    Memory address}\\\\\\\textt{1 \ bit  \  \ \ \ \ \ 128  \ \ \ \ \ \ \ \ \ \ \ \ \ \ \    2 \ bits   \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \   24 \ bits  \ \ \ \ \ \ \ \ \ \ \ \ \ \ \  \ \ \ \ \ \ \ \ \           30 \ bits}\\\\\\            = 2^7 \\\\ = 7 \ bits

calculating the register Bits:

= 64-(1+7+24+30)\\\\=64 -62\ \  bits\\\\= 2\ \ bits\\

C)

Immediate value size while merging the additional benefit with the address field:

= 2^{24} + 2^{30}\\\\= 2^{54}\\\\\texttt{Range before combining(-,+) 24 bits   \ \ \ \ \ \       Range after combining( -,+)54bits}\\\\                         \textt{-2^{12} from + (2^{12}-1)   \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \                                    -2^{27} from + (2^{27}- 1)}

= \frac{24}{2} = 12\\\\= \frac{54}{2} = 27

The range is accomplished by dividing the bits by 2 into the two sides of the o and the number is one short to 0.

KengaRu [80]

Uses of excels

1.    Personal fitness log: log the things you eat along with its calories and record it every day. Make a pivot of the data and see how much you have consumed. Along with this, add sleep duration, and measure the number of hours that you have slept each day during the month.

2.     Budget Planner: Make a monthly budget and maintain a log of things you buy in order to keep a track of your budget. This will help to keep a track and you will be more or less in the limits of the budget allocated during the start of the month.

3.    Headache Log: If you experience frequent headaches, then log that and when there is enough data a comparison can be done.

You can make charts and other graphical representations of the data to compare and contrast your trends and can make an efficient analysis. All these features which are present in excel are not available in other applications all at one time.
