Let
be the population mean.
For the given claim , we have
Null hypothesis : 
Alternative hypothesis : 
Since alternative hypothesis is two-tailed , so the test is a two-tailed test.
Given : Sample size : n=220 ;
Sample mean:
;
Standard deviation: 
Test statistic for population mean:


By using the standard normal distribution table of z , we have
P-value ( two tailed test ) : 

Since , the P-value is greater than the significance level of
, it means we do not have sufficient evidence to reject the null hypothesis.
