Answer:
<u>The standard error of the mean is 0.444</u>
Step-by-step explanation:
1. Let's review the information given to us for solving the question:
Size of the sample = 25
Mean amount of money spent per day = US$ 18.01
Standard deviation = US$ 2.22
2. For finding the standard error of the mean, we use the following formula:
Standard error = Standard deviation / √Size of the sample
Standard error = 2.22 / √25
Standard error = 2.22 / 5
<u>Standard error = 0.444</u>
3. Interpretation of the standard error:
The standard error is "the standard deviation of the population of values of a sample statistic in a repeated sampling or its estimate".
Thus, the potential for error in the reported result is not more than ± 0.444 (68% confidence) or no more than 1.96 times the standard error (0.444) = ± 0.87 (at 95% confidence).
Step-by-step explanation:
1. 48 decide by 16 = 3 per min
2. Decide by 7 you will get 5:2
3. 24 per hour so 3 hours is 3 times 24 which is 72
4. 5cm per hour
5. 175:326.
6.1080 decide by 9 you get 120
120 times 13 is 15607.
7. 2520 decide by 9 is 280
Sara got 560 while Hina got 19608.
8. Ali is the fastest. He can fold 8 in a minute
9. I dont understand your question
10. A is 3
Answer:
would that be 264.1
Step-by-step explanation:
Answer:
The method of finding the total outcomes of an event allows you to see all possible outcomes is tree diagram.
7√27 + 5√48 in simple radical form
41 sqrt(3)
√27 can be written as √(3*3^2) = 3√3
√48 can be written as √(3*4^2) = 4√3
so 7√27 + 5√48 = 7*3√3 + 5*4√3 = 21√3 + 20√3 = 41√3
