At the alternate hypothesis, we test if it is greater than 0.7, that is:
The test statistic is:
In which X is the sample mean, is the value tested at the null hypothesis, s is the standard deviation and n is the size of the sample.
0.7 is tested at the null hypothesis:

Survey of 35 people. From the sample, the mean difference was 0.95, with a standard deviation of 0.44.
This means that
Calculate the test statistic
The test statistic is t = 3.36.
