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:
The equal sign "=" must be used.
Most, if not all, spreadsheet programs support formulas, but you must start them with an equal sign.
Answer:
S
Explanation:
The index operator will address individual characters in the string.
Explanation:
Age = 23.
To convert a base 10 number to hexadecimal number we have to repeatedly divide the decimal number by 16 until it becomes zero and store the remainder in the reverse direction of obtaining them.
23/16=1 remainder = 5
1/16=0 remainder = 1
Now writing the remainders in reverse direction that is 15.
My age in hexadecimal number is (15)₁₆.
Answer:
Here is the program:
current_time = '2014-07-26 02:12:18:'
my_city = ''
my_state = ''
log_entry = ''
my_city = input("") #reads in value for my_city
my_state = input("") #reads in value for my_state
log_entry = current_time + ' ' + my_city + ' ' + my_state #concatenates current_time, my_city and my_state values with ' ' empty space between them
print(log_entry)
Explanation:
You can also replace
log_entry = current_time + ' ' + my_city + ' ' + my_state
with
log_entry = f'{current_time} {my_city} {my_state}'
it uses f-strings to format the strings
If you want to hard code the values for my_city and my_state then you can replace the above
my_city = input("")
my_state = input("")
with
my_city = "Houston"
my_state = "Texas"
but if you want to read these values at the console from user then use the input() method.
The screenshot of the program along with the output is attached.
