Step 2: Navigate to the Data Analysis option in the left-most corner of the tab and click on it. Learn more about us. The objective is to compute the mean and the standard deviation from an array. import scipy.stats as stats import math # Specify the sample mean (x_bar), the sample standard deviation (s), the mean claimed in the null-hypothesis (mu_null), and the sample size (n) x_bar = 62.1 s = 13.46 mu_null = 55 n = 30 # Calculate and print the test statistic The output you are looking for can be achieved using the COUNT function in excel. To solve a math equation, you need to find the value of the variable that makes the equation true. hypothesis? To assess statistical significance, examine the test's p-value. 147.83.101.8 two-tailed test, the P-value is the probability that a Atlanta.
