Answer:
a. count of observations that meet a condition (counts), total number of observations (nobs), Hypothesized value of population proportion (value).
Explanation:
In other to use the proportion_ztest method, the need to make import from the statsmodel module ; statsmodels.stats.proportion.proportions_ztest ; this will allow use use the Z test for proportion and once this method is called it will require the following arguments (count, nobs, value=None, alternative='two-sided', prop_var=False)
Where;
nobs = number of observations
count = number of successes in the nobs trial or the number of successes for each independent sample.
Value = hypothesized value of the population proportion.
Cache memory is a high-speed memory that stores the instructions and data that have been frequently accessed. It decreases the time it takes to decode the instructions stored in the instruction pipeline.
A. It decreases the time it takes to decode instructions stored in the instruction pipeline.
<u>Explanation:</u>
Whenever an instruction is invoked or some data is accessed, the CPU looks for it in the cache memory before accessing the main memory.
If the content is found in the cache memory, it accessed from there and then and hence the access time and decode time is reduced as there were no main memory lockups.

Answer:
pgp --encrypt "my-message.txt" --recipient (Sean) --output ("secret-message.txt.gpg")
Explanation:
PGP encryption from the command line can be done using the following format:
- pgp --encrypt (input) --recipient (user) --output (output file)
Therefore, PGP command line syntax to encrypt the my-message.txt file for a specific user (Sean) and save the output as secret-message.txt.gpg is:
- pgp --encrypt "my-message.txt" --recipient (Sean) --output ("secret-message.txt.gpg")
A PCM system consists of a PCM encoder (transmitter) and a PCM decoder (receiver). The essential operations in the PCM transmitter are sampling, quantizing and encoding. All the operations are usually performed in the same circuit called as analog-to digital convert Early electrical communications started to sample signals in order to multiplex samples from multiple telegraphy sources and to convey them over a single telegraph cable. The American inventor Moses G. Farmer conveyed telegraph time-division multiplexing (TDM) as early as 1853. Electrical engineer W. M. Miner, in 1903, used an electro-mechanical commutator for time-division multiplexing multiple telegraph signals; he also applied this technology to telephony.
