The breaking strength of Brand Ă Cohon thread is larger Brand Hi! The breaking Strength of Brand Á cotton thread is equal smaller than Brand Bi 2) we (ii) t- test with non -poded estimate. Because sample size is small i,.., 10 hence f-test and 2- tesh Because two-brands are different and independent they have variances See the standard deviations too different (3) P-value ID02 and M: 0.05. SO p-value 10.05 we failed to reject Ho that the breaking strength of brand K cotton thread larger than Brand 'B' I error Reject Ho when it is true Accepting Ho is talse. Here type lerror = 0.05 (small) and therefore, type 2 error be larger and we might have made that error because up accepling are we Ho and that is because ob Small sample Size: are os can say ? 14 Type Type 2 error when it 1 will ending Type l error. And we si increase FOY (5) in sample size from io to so.

. Pi is correct. Ha should be ua sup i instead of ua aub. Pe is incorrect the difference between so is too large, we cannot assume that variance are equal Pu did not mention which type of error we might might make Ps is incorrect with such instead of to test * I hope this answer will please give up avote bor my work, a large sample sige, should apply 2- test helpful for you
