(a) The standard error of the mean (SEM) for the U.S. babies is 0.083.
(b) An approximate 95% confidence interval for the mean sleep time for 6-month-old babies in the United States is 12.8367< μ1< 13.163.
(c) An approximate 95% for the difference in average sleep time for 6-month-old Dutch and U.S. infants is −2.203< μ1 <μ2 < −1.7969.
What is standard error and how it is measured?
A statistical concept known as the standard error uses standard deviation to assess how accurately a sample distribution represents a population. The standard error of the mean describes the statistical variation between a sample mean and the population's actual mean.
According to the given information:
In United States:
Sample size 
Mean, 
Standard deviation, 
In Netherlands:
Sample size, 
Mean, 
Standard deviation, 
(a) For the newborns in the United States, the standard error of the mean (SEM) is determined as follows:
(b) The following formula is used to determine the 95% confidence interval for the mean sleep time for babies aged 6 months in the United States:
(c) The 95% difference in the amount of time newborns in the Netherlands and the United States spend sleeping on average is computed as follows:

Answer:
Following are the code to this question:
def binarynumber(num):#defining a method binarynumber that accepts a parameter num
x=""#defining a string variable x
if (num!=0):#defining if condition to check number not equal to 0
while (num>=1):#defining a loop that check value is grater then equal to one
if (num %2==0):#defining if condition to check num is even
x=x+"0" #add string value 0 in num variable
num=num/2 #divide the value by 2
else:#defining else block
x=x+"1"#add string value 1 in num variable
num=(num-1)/2#first subtract 1 into num variable then divide the value by 2
else:
x="0"#assign string value 0 in num variable
return "".join(reversed(x))#return value
num = int (input ("Enter any number: "))#defining num variable that input the integer value
print (binarynumber(num))#using print method to call method binarynumber with passing num parameter
Output:
Enter any number: 12
1100
Explanation:
- In the above python code a method "binarynumber" is declared, in which the "num" variable passes as the parameter inside the method a string variable "x" is declared that stores all converted values.
- Inside the method and if the block is declared that checks number value is not equal to 0 if this condition is false then it will add string value and reverse its value.
- Or if the condition is true it defines a while loop that calculates the given number binary digits and returns its value.
- At the last step, the num variable is declared that inputs the integer value from the user end and calls the method by using the print method.

Apply handrub to palm of one hand.
Rub hands together covering all surfaces of hands and fingers.
Rub until handrub is absorbed.
Answer:
i think Make variables to represent the length and width of a rectangle, called length
and width
, respectively. You should set length
to 10 and width
to 5.
Then, write some mathematical expressions to computer the area and perimeter of the rectangle and save these values inside variables named area and perimeter
.Use print
statements to display the area and perimeter of the rectangle.
Your output should print the area on the first line and the perimeter on the second, like this:
50 30 Rectangle Area Formula:
Area = L * W
