Answer:
E. When the sample size increases, because the standard deviation of the distribution of sample means better estimates the population standard deviation for larger sample sizes.
Step-by-step explanation:
- T distribution is similar to the normal distribution and is seen when the estimates of the variance are based on the degree of freedom and has a relatively more score in its tail and has a greater change of extreme values.
Answer: 1000000
Step-by-step explanation:
So first you would need to time 5 and 4.33 then divide by 2 then times by 3 cause there are 3 triangles. it would equal C.
The probability that a student uses the Internet, given that he or she is in eighth grade is 8/13 or 0.66
<u>Step-by-step explanation:</u>
<u>From the table shown:</u>
- The students in the eighth grade = 13
- The eighth grade students using internet = 8
P(student uses the Internet in eighth grade) = P(eighth grade students using internet) / P(total students in the eighth grade)
⇒ 8/13
⇒ 0.66
