The null hypothesis,H0:u=48,was tested against the alternative hypothesis,H1:u>48.A sample of 75 resulted in a calculated pvalue of 0.102.if standard deviation=3.5,the value of the sample mean is?need help

Using the ztest formula, solve for sample mean:
z = (sample mean  population mean)/(standard deviation divided by the square root of the sample size)
Find z in a ztable using pvalue. Population mean is 48. Standard deviation is 3.5 and sample size is 75.
I'll let you take it from here.
