Answer:
For a given confidence level, t* is never smaller than z*.
Step-by-step explanation:
t* and z* are the critical value of a confidence interval. For example, at 95% confidence, z* = 1.96. This is because 95% of a normal curve is within ±1.96 standard deviations.
A student's t distribution has the same bell-curve shape as a normal distribution, but is shorter and wider, which is why t* is always larger than z*. As the sample size increases to infinity, the distribution approaches normal.

what is 6 . 97 130 103 103 please specify
am I multiplying dividing...
The 87th term of the arithmetic sequence 12, 0, -12 is -1020. The ratio being -12 and the first term being 12.
A conclusion which can be derived from these random samples is that: B. the students in grades 11 and 12 scored higher than the students in grades 9 and 10.
<h3>What is a median?</h3>
A median can be defined as the middle number (center) of a sorted data set, which is when the data set is arranged in from the greatest to least or the least to greatest.
In Mathematics, the median of a data set is generally considered to be a better measure of center than the mean when there's an outlier in the data set.
Based on the information provided for these samples, we can logically conclude that the students in grades 11 and 12 scored higher than the students in grades 9 and 10 because a median score of 86 is greater than a median score of 79.

So then he makes 12 monthly payments of $60 each so he pays 12 times 60 or 720
you then add this to the deposit, which was 315 and get how much he paid or 1035
then you subtract how much the marked price was from how much he paid or $900-$1035=135
