Answer:
a. 0.50
Step-by-step explanation:
The standard error of the mean is the standard deviation of the population divided by the square root of the sample size.
In this problem, we have that:
Standard deviation of the population: 6 hours
Sample size: 144
Square root of 144 is 12.
So the standard error of the sample mean is 6/12 = 0.5.
Answer:
The answer to your question is: Japan
Step-by-step explanation:
Mobile cost in Spain = € 352.5
Mobile cost in Japan = ¥39856
Exchange rate = £1 = €1.41
£1 = ¥188
Cost of mobile in pounds
£ 1 ------------------ € 1.41
x ----------------- €352.5
x = (352.5 x 1) / 1.41
x= £250
£1 ------------------ ¥188
x ----------------- -¥ 39856
x = (39856 x 1) / 188
x = £212
Then, it was cheaper in Japan
796,000/2388=10,000/x
796,000x= (2388*10,000)
796,000x/796,000=23,880,000/796,000
x=30 births

Answer:
Step-by-step explanation:
Given
Yearly Cost for members; 
Required
Determine the yearly cost for non members
From the question, we understand that:
<em>A non member pays $0.20 for each game;</em>
Yearly cost is then calculated as thus;
y = Amount * Number of Games
Where:
Amount = $0.2 and Number of Games = x
Convert 0.2 to fraction
Divide the numerator and the denominator by 2
<em>Hence, the yearly cost for non members is </em>
