They can be used to just copy/paste e-mailed information without writing down on a paper and losing valuable time. This is one example.
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:
True
Explanation:
The while loop is going to be executed until the condition is false.
Since <em>k</em> is initially equal to 1, the loop will execute 88 times. One asterisk will be printed and <em>k</em> will be incremented by one during each iteration.
When <em>k</em> becomes 89, the condition will be false (89 is not smaller or equal to 88) and the loop will stop.
Data visualization
Data visualization is a good starting point for data mining. There are several approaches to data mining that supports smart decisions. Data visualization places data in a visual context. It extracts the data in a clear and understandable way without any form of reading or writing. Results are displayed in the form of pie charts, graphs, and any other statistical representation. Such multidimensional views of data aid in developing a preliminary understanding of the trends that are hidden in the data set.
