For a standard normal distribution, the value of the z-score represented as c in P(-0.78≤Z≤c)=0.7657 is 0.0166
<h3>How to find the p-value from 2 z-scores?</h3>
We want to find the p-value between 2 z-scores expressed as;
P(-0.78 < z < c) = 0.7657
To solve this, we will solve it as;
0/7657= 1 - [P(z < -0.78) + P(z > c)]
From normal distribution table, we have that;
P(z < -0.78) = 0.217695
Thus;
0.7657 = 1 - (0.217695 + c)
c = 1 - 0.7657 - 0.217695
c = 0.0166
Thus, For a standard normal distribution, the value of the z-score represented as c in P(-0.78≤Z≤c)=0.7657 is 0.0166

Answer:
14.06 Riyals
Step-by-step explanation:
Given:
The exchange rate 3.7 Riyals for $1.
And Carlos exchanged $3.80.
We need to find how many Riyals would he get if he exchanged $3.80.
The exchange rate of $1 = 1
3.7 = 3.7 Riyals
For $2 = 2
3.7 = 7.4 Riyals
Similarly for $3.80 = 3.80
3.7 = 14.06 Riyals
Therefore, the exchange rate of $3.80 is 14.06 Riyals.
