The value of x^2
K The normal quantile plot or a chi-squared test can be used to check for normality. For that, data are grouped into bins, converting numerical data into categorical data. The accompanying figure shows the norm quantile plot of daily stock returns on the value-weighted total market index for a country. The accompanying table counts the number of returns falling into 8 intervals. The table includes the count expected un the assumption that these data are normally distributed, using the sample mean x=0.0009629 with SD=0.0161. Complete parts a through e below. Click the icon to view the normal quantile plot of daily stock returns. Click the icon to view the table of 10/11 OA. The sample mean would decre OB. The expected counts would be C. The expected counts would be OD. The standard deviation of the (c) Compute the chi-squared test of go hypotheses for this test. OA. Ho: The stock returns have eq Ha: The stock returns have no OC.
