Result: Actually‚ it can be obviously seen that the female has more frequency to be survived than male. Also‚ the 1st class of passengers are less frequency to be died but 3rd class of passengers are more frequency to be died. Quoting some two-test statistic‚ the degree freedom is 456. The t is 1.047 and the p-value is 0.2957 which >0.05 and does not reject Ho. Conclusion: In conclusion‚ the determinant of Sex can affect the survival of passengers as it can be considered in the first graph. The

Statistics Essay Mean is the arithmetic average of a distribution‚ obtained by adding the scores and then dividing it by the number of scores there are. Median is the middle score in a distribution; half the scores are above it and half the scores are below it. Mode is the most frequently occurring score in a distribution. A skewed distribution is when the distribution is leaning toward one side. It is the measure asymmetric probability and its real value of data. A skewed would be like a group

strong evidence that the gambler’s claim is true? a. Specify the null and alternative hypothesis for this problem. p = probability gambler guess correctly for an individual roll null (Ho): p = 1/6 alternative (Ha): p > 1/6 b. Find the test statistic and calculate the p-value. What do you conclude? pˆ = 0.2 so z = (0.2-0.1667)/ .1667(.8333) /100 = 0.894. From the table the p-value is between 18% and 19%. The null hypothesis is a reasonable explanation of this data so we do not have strong evidence
