Answer:
243
Step-by-step explanation:
999-100= 899 integers
200s 400s 600s 800s excluded so 400 numbers excluded
899 - 400 = 499
20s 40s 60s 80s which are 40 integers x 4 = 160
499 - 160 = 339
2s 4s 6s 8s which are 4 integers x 6 x 4 ( 4 from each 100 ) = 96
339 - 96 = 243 integers
This problem tackles the place values of numbers. From the rightmost end of the number to the leftmost side, these place values are ones, tens, hundreds, thousands, ten thousands, hundred thousands, millions, ten millions, one hundred millions, and so on and so forth. My idea for the solution of this problem is to add up all like multiples. In this problem, there are 5 multiples expressed in ones, thousands, hundred thousands, tens and hundreds. Hence, you will add up 5 like terms. The solution is as follows
30(1) + 82(1,000) + 4(100,000) + 60(10) + 100(100)
The total answer is 492,630. Therefore, the number's identity is 492,630.
Answer:
The most appropriate inferential statistic test in the present situation is the;
b. Two-sample t-test
Step-by-step explanation:
From the question, we have;
The number of subjects in each sample, n₁ = 100
The number of samples = 2
The nature of the test = To compare the two means
The value of the population standard deviation, σ = Unknown
From the given parameters, we have;
The t-test is a method of inferential statistics for determining whether the difference between the mean of two groups is significant, that is if the observed difference are due to chance, where the groups are likely to have some characteristics that are related
The t-test is utilized when testing an hypothesis, and it is used for small samples, where the population standard deviation is unknown
The types of t-test used are;
a) One-sample t-test
b) Two-sample t-test
c) Paired Sample t-test
Therefore, a two-sample t-test is most appropriate.
