A standardized test was given to a set of high school juniors and the distribution of the data is bell shaped. The mean score is

stira [4]

Answer:

920 points.

Step-by-step explanation:

We have been given that the mean score for a standardized test is 800 and the standard deviation is 120. To qualify for a special summer camp for accelerated students, a student must score within the top 16% of all scores on the test.

First of all we will find probability of 0.16 using normal distribution table.

Using normal distribution our Z score will be 0.994458

Now we will use raw-score formula to find the score (x) that a student must make to qualify for summer camp.

$x=\text{Mean}+\text{ Standard deviation* Z score}$

Upon substituting our given values in above formula we will get,

$x=800+120\times 0.994458$

$x=800+119.33496$

$x=919.33496$

Upon rounding to nearest whole number we will get,

$x=920$

Therefore, a student must make 920 points to qualify for summer camp.

Simplify -6 . 2 041 318 4 8 318

PilotLPTM [1.2K]

$- 6 \frac{1}{4} - ( - 2 \frac{1}{8} )$

$= - 6 \frac{1}{4} + 2 \frac{1}{8}$

$= \frac{ - 25}{4} + \frac{17}{8}$

$= \frac{ - 50}{8} + \frac{17}{8}$

$= \frac{ - 50 + 17}{8}$

$= \frac{ - 33}{8}$

$= - 4 \frac{1}{8}$
