Use the z-score formula, z=x−μσ, and the information below to find the mean, μμ. Round your answer to one decimal place, if necessary. z=1.25, x=21.3, and σ=1.2

Please indicate whether the above scatter plot indicates an r value that is: a. close to r=-1 b. close to r=+1 с. clearly negative but not near r = -1 d. clearly positive but not near r = +1

Find the z-score that best satisfies the condition. 10% of the total area is to the left of z. 2=0 (Round to the nearest hundredth.)

Many colleges assign numerical points to grade as follows: A = 4, B=3, C=2, D=1, and F=0. Calculate the grade point average. Round to two decimal places, as needed. Course Credits Grade English 4 B Speech 2 :D Mathematics History :3 Physics

Find the z-score corresponding to the given value and use the z-score to determine whether the value is significantly low or high.  Consider a score to be significantly low if its z-score is less than  or equal to -2.  Consider a z-score to be significantly high if it is greater than or equal to 2.  Round the z-score to the nearest tenth if necessary. A body temperature of 96.7° F given that human body temperatures have a mean of 98.20° F and a standard deviation of 0.62°.
