1. Refer to the Preview 12 Part 23.A to enter the mean, standard deviation, and sample size foe each type of solar panel, and then calculate the variance for each of the three types of panels and place the results in the table below. Round variance values to the Ernearest tenths place. Fixed Tracking Concentrated Mean Standard Deviation Sample size Variance a) Variance is the square of standard deviation. The symbol s represents the variance of the sample means given. Compute the value. Round to the nearest hundredths place. b) The sample means computed above are from populations that are assumed to have identical distributions, so their variance from (a) is an estimate of the standard error of sample means, of. Estimate the population variance using o = n * $;. c) Another way to estimate the population variance when the sample sizes are equal is by averaging the sample variances, s'. We refer to the mean of samples variances as the pooled variance, so?. Estimate the population variance with the pooled sample variance. d) When all samples have the same size, the F-test statistic for the one-way ANOVA is the ratio of these estimates of of. F _ But Compute the F-statistic for this test. e) Find the numerator and denominator degrees of freedom and use technology to find the P-value
