Answer:
The two readings that are cutoff values are T=1.84 deg C and T=-1.84 deg C.
Step-by-step explanation:
Thermometers rejected by measurements above normal represent 3.3% of the total, which indicates, by normal probability distribution data, that accepted thermometers are 96.7% likely to measure less than the maximum allowable temperature.
This value (P(X>x)=0.967) corresponds to z = 1.8388. Since the mean and standard deviation values are the same as the standard normal probability distribution (mean = 0, sd = 0), the z value is equivalent to the measured value (temperature).
Given the symmetry of the probability distribution, we can affirm that the thermometers rejected by measurements below the permissible measured a temperature lower than -1.8388.
Answer:
x = 3.391
Step-by-step explanation:
first you calculate.
7.9% - 0.25 = 3.22 + x
divide the numbers
- 0.25 = 3.22 + x
calculate again.
0.079 - 0.25 = 3.22 + x
move the terms
<u>-0.171</u> = <u>3.22 + x</u>
add the numbers
<u>-x = 3.22 + 0.171</u>
then change the signs
<u>-x = 3.391</u>
Final ans : <u>x = -3.391</u>
or some alternate answer's
x = - , x = -3
