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
