Question
TODO 1: Using the Matplotlib plt.plot() function, plot the x values and y values. As seen in the illustration, a normal distribution should be drawn!
# TODO 1
plots = plt.plot(x_values, y_values)
Expected Output:

Transcribed Image Text:The image showcases a graph of a normal distribution, also known as a Gaussian distribution. The curve is symmetric and bell-shaped, centered around the mean, which in this case is zero.
Key details of the graph:
- **X-axis (Horizontal):** Represents the standardized values or z-scores, ranging from -4 to 4.
- **Y-axis (Vertical):** Displays the probability density, ranging from 0.00 to 0.40.
- **Curve**: The peak of the graph occurs at the mean (0), indicating the highest probability density. As the curve moves away from the mean, it gradually approaches zero, illustrating the properties of the normal distribution where values far from the mean are less probable.
This graph is an essential concept in statistics, emphasizing the significance of normal distribution in various fields such as psychology, finance, and natural sciences.

Given a JSON string provided by the web service, this function returns True if thequery failed and there is an error message.

On the other hand if the json is '{"success": true, "src": "2 United States Dollars", "dst": "1.772814 Euros", "error": ""}' then this function returns False.

The function must compute and return the True Positive Rate (TPR, also called recall) and the False Positive Rate (FPR) for each threshold value in the threshold value list that is passed to the function. Important: Be sure to reuse functions and code segments from your work above! You should reuse two of your above created functions so that you do not duplicate your code. The function you will write behaves identically to Scikit-Learn's roc_curve function, except that it will take the list of thresholds in as input rather than return them as output. Your function must calculate one value of TPR and one value of FPR for each of the threshold values in the list.…arrow_forward
- Write a function that returns the greatest common divisor of 2 integers.arrow_forwardComplete the rotate_text() function that takes 2 parameters, a string data and an integer n. If n is positive, then the function will shift all the characters in data forward by n positions, with characters at the end of the string being moved to the start of the string. If n is 0 then the text remains the same. For example: rotate_text('abcde', rotate_text('abcde', rotate_text('abcde', 1) would return the string 'eabcd' 3) would return the string 'cdeab' 5) would return the string 'abcde' rotate_text('abcde', 6) would return the string 'eabcd' ... and so on. If n is negative, then the function will shift the characters in data backward by n positions, with characters at the start of the string being moved to the end of the string. For example: rotate text('abcde', -1) would return the string 'bcdea'arrow_forwardProblem Statement: In tennis, a set is finished when one of the players wins 6 games and the other one wins less than 5, or, if both players win at least 5 games, until one of the players wins 7 games.
