- find the standard deviation step by step. that is find the deviation of each observation from the mean, square the deviations then obtain the variance and the standard deviation.i found the mean : 10.05i need help finding the standard deviation and the varianceWhich of the following are true about the normal curve? Check all that apply. The normal curve is skewed to the right. The normal curve is unimodal. The normal curve touches the horizontal axis. The normal curve is symmetricalDetermine whether the statement is true or false. If it is false, rewrite it as a true statement. As the size of a sample increases, the standard deviation of the distribution of sample means increases. Choose the correct choice below. C OA. This statement is false. A true statement is, "As the size of a sample increases, the standard deviation of the distribution of sample means decreases." OB. This statement is true. OC. This statement is false. A true statement is, "As the size of a sample decreases, the standard deviation of the distribution of sample means decreases." OD. This statement is false.

- (2) Please help me answer this one. Refer to the photo for your guide. Read the instructions and directions very carefully. Type only your answers, please do not handwritten.Use the given data values (a sample of female arm circumferences in centimeters) to identify the corresponding z scores that are used for a normal quantile plot, then identify the coordinates of each point in the normal quantile plot. Construct the normal quantile plot, then determine whether the data appear to be from a population with a normal distribution. 44.2, 34.5, 38.2, 32.7, 40.9 Part A- List the z scores for the normal quantile plot. Part B- Identify the coordinates of each point in the normal quantile plot. Use ordered pairs for the form (x,y), where x is the sorted arm circumferences in ascending order, and y is the corresponding z score. Part C- Do the data come from a normally distributed population?
