blisters until healing is complete.

Test the hypothesis, at the $5\%$ significance level, that there is no difference between the four treatments with respect to mean time of healing.

Use SPSS output attached Anova$2.$pdf and choose only $5$ correct answers from the following statements:

The null and alternative hypothesis are: $H_0$:${}_1={}_2={}_3={}_4$;$H_1$ : All population means differ

The null and alternative hypothesis are: $H_0$:${}_1{}_2{}_3{}_4$;$H_1$:${}_1={}_2={}_3={}_4$

The null and alternative hypothesis are: $H_0$:${}_1={}_2={}_3={}_4$;$H_1$ : At least two population means are not equal

The null and alternative hypothesis are: $H_0$:${}_1={}_2={}_3={}_4$;$H_1$:${}_1{}_2{}_3{}_4$

The test statistic is: $10\mathrm{.}267$

The test statistic is: $4\mathrm{.}478$

The test statistic is: $1\mathrm{.}325$

The test statistic is: $7\mathrm{.}748$

The p$-$value is: $0\mathrm{.}002$

The p$-$value is: $0\mathrm{.}049$

The p$-$value is: $0\mathrm{.}027$

The p$-$value is: $0\mathrm{.}435$

The decision using $5\%$ significant level is: Reject the null hypothesis and accept the alternative which states there is no difference in mean time between treatments

least two treatments

The decision using $5\%$ significant level is: Accept the null hypothesis which states there is no difference in mean time between treatments

The decision using $5\%$ significant level is: Accept the null hypothesis which states that there is significant difference in mean time between treatments

The significant difference in mean time between treatments: A and B

The significant difference in mean time between treatments: A and B$,$ C$,$

The significant difference in mean time between treatments: A and B$,$ C$,$ D

The significant difference in mean time between treatments: All of them
