What is the area to the right of one?

Short Answer

Expert verified

The area to the right of one represented as $P (x > 1)$ or $1 - P (x < 1)$

Step by step solution

Given information

Given in the question that, a graph

We have to find what is the area to the right of one

Explanation

Consider the given graph:

The shaded area in the given graph shows the area to the right of $x$

The area is represented by the probability localid="1648295524318" $P (x > x)$

Suppose X ~ N(12, 6). What is the z-score of x = 2?

Suppose that the distance of fly balls hit to the outfield (in baseball) is normally distributed with a mean of 250 feet and a standard deviation of 50 feet.

a. If $X =$ distance in feet is for a fly ball, then $X ~$

b. If one fly ball is randomly chosen from this distribution, what is the probability that this ball will travel fewer than 220 feet? Sketch the graph. Scale the horizontal axis $X$ Shade the region corresponding to the probability. Find the probability.

c. Find the $80^{ith}$ percentile of the distribution of fly balls. Sketch the graph, and write the probability statement.

A The distance of fly balls hit to the outfield in baseball is denoted as: $N ~ N (250, 50)$

B: The probability that a randomly selected fly ball traveled fewer than 220 feet is given by $P (x < 220) = 0.2743$

The length of time it takes to find a parking space at 9 A.M. follows a normal distribution with a mean of five minutes and a standard deviation of two minutes.

Find the probability that it takes at least eight minutes to find a parking space.

a. 0.0001

b. 0.9270

c. 0.1862

d. 0.0668

About what percent of $x$ values lie between the second and third standard deviations (both sides)?

a. Suppose a $15$ to $18$ -year-old male from Chile was $176 c m$ tall from $2009$ to $2010$ . The z-score when $x = 176$ cm is $z =$ _______. This $z -$ score tells you that $x = 176 c m$ is ________ standard deviations to the ________ (right or left) of the mean _____ (What is the mean?). b. Suppose that the height of a $15$ to $18$ -year-old male from Chile from $2009$ to $2010$ has a $z$ -score of $z = - 2$ . What is the male’s height? The $z$ -score $(z = - 2)$ tells you that the male’s height is ________ standard deviations to the __________ (right or left) of the mean.
