Answer:
Executing multivalued attribute in
database:
Multivalued attributes are not directly
implemented in Relational Database,
instead of that follow the below possible
actions:
Explanation:
Multivalued Attributes
A multivalued attribute of an entity is an attribute that can have more than one value associated with the key of the entity. ... If attributes are restricted to be single valued only, the later design and implementation decisions will be simplified.
Example:
Consider a person can have multiple
degrees values like BSC, MCA and these
values can be stored in single attribute in a
database.

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.
Answer:
a: Twisted pair won't span a 400-foot distance.
Explanation:
The maximum distance that twisted pair cables can support without attenuation is 100 meters which is approximately 328 feet and the two office buildings are 400 feet apart, so it is useless to install a twisted pair cable for such a large distance. A much better option would be to install optic fiber. Though it is a bit expensive but it is the best option in this case.
Hence option (a) is the correct reason for installing an optic fiber cable rather than a twisted pair cable.
Generally I'd recommend not buying one online, tends to be cheaper from a shop - and better used, although their are some risks with 2nd hand devices, I think the big price cut it worth it.
If you did want to buy online, maybe Amazon or Ebay?
