Use the information given below to find the P-value Then, use a 0.05 significance level and state the conclusion about the null hypothesis (reject the null hypothesis or fail to reject the null hypothesis) The test statistic in a left-tailed test is z= -1.82. Find the P-value. Hint: The P-value is the area in the tail(s) of the standardized test statistic. Since we are given a z-score, we can use normalcdf to find the area in the tail(s) P-value (Round to four decimal places as needed.) State the conclusion about the null hypothesis. Choose the correct answer below. A. Fail to reject the null hypothesis. The P-value is less than the level of significance. B. Reject the null hypothesis. The P-value is less than the level of significance. C. Reject the null hypothesis. The P-value is greater than the level of significance. D. Fail to reject the null hypothesis. The P-value is greater than the level of significance.

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
