Step-by-step explanation:

a) it is true that the bigger the sample size, the more accurate the reported average of the sample. An increased sample size gives a smaller standard deviation. This improves accuracy.

b) It is false. A type 1 error occurs when a true null hypothesis is rejected

c) It is true. The null hypothesis is considered true until the alternative hypothesis which is contrary is favoured by sufficient evidence.
