State the necessity of exponentiaily moving weighted average. In batch norm, the mean and variance at test time are calculated using the means andvariances of various mini batches at training time using exponentiality moving weighted average. The means across four minibatches at training timeare 0.78, 0.92, 0.82, and 0.29 respectively. The variances across the same four minibatches are 0.14, 0.12, 0.1, and 0.37 respectively. Compute the meanand variance at test time with and without bias correction. What conclusions can you draw based on the obtained results? Momentum hyperparameterFiis 0.9.

The given means are 0.78, 0.92, 0.82 and 0.29 The given variances are 0.14, 0.12, 0.1 and 0.37 We…

A researcher takes sample temperatures in Fahrenheit of 20 days from Minneapolis and 18 days from Cleveland. Use the sample data shown in the table. Test the claim that the mean temperature in Minneapolis is different than the mean temperature in Cleveland. Use a significance level of α=0.01. Assume the populations are approximately normally distributed with unequal variances.Note that list 1 is longer than list 2, so these are 2 independent samples, not matched pairs.

According to Zero Population Growth, the average urban U.S. resident consumes 3.3 pounds of food per day. Is this figure accurate for rural U.S. residents? Suppose 64 rural U.S. residents are identified by a random procedure and their average consumption per day is 3.60 pounds of food. Assume a population variance of 1.31 pounds of food per day. Use a 5% level of significance to determine whether the Zero Population Growth figure for urban U.S. residents also is true for rural U.S. residents on the basis of the sample data.
