Write an equation in standard form of the line that is
2 answers:
What is boxed is what you put in your stat plot in your calculator (graphing). To find the y intercept you use the value function on your calculator (if you have a Ti-84 it’s 2nd-> trace-> 1) and enter 0. Yo find the x intercept you use the zero function on your calculator (if you have a Ti-84 it’s 2nd-> trace-> 2 and follow the instructions it asks). Hope this helps!

The z-score of the considered newborn having 4,000 g weight is
If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z score.
If we have
(X is following normal distribution with mean and standard deviation
)
then it can be converted to standard normal distribution as
(Know the fact that in continuous distribution, probability of a single point is 0, so we can write
Also, know that if we look for Z = z in z tables, the p value we get is
For the considered case, the statement in the problem is missing the mean weight of the newborn and standard deviation of the data set of weights of newborn.
Thus, for them, we can consider variables in place of their actual values.
Let we have:
- X = weights of newborns for some considered system (in grams)
= mean weight of newborns (in grams)
= standard deviation of the data set of weights of newborns
Then, the z-score for X = 4000 is
Thus, the z-score of the considered newborn having 4,000 g weight is
