Performs a Welch's t-test and calculates p-values between two groups.

`ttest_protti(mean1, mean2, sd1, sd2, n1, n2, log_values = TRUE)`

- mean1
a numeric vector that contains the means of group1.

- mean2
a numeric vector that contains the means of group2.

- sd1
a numeric vector that contains the standard deviations of group1.

- sd2
a numeric vector that contains the standard deviations of group2.

- n1
a numeric vector that contains the number of replicates used for the calculation of each mean and standard deviation of group1.

- n2
a numeric vector that contains the number of replicates used for the calculation of each mean and standard deviation of group2.

- log_values
a logical value that indicates if values are log transformed. This determines how fold changes are calculated. Default is

`log_values = TRUE`

.

A data frame that contains the calculated differences of means, standard error, t statistic and p-values.

```
ttest_protti(
mean1 = 10,
mean2 = 15.5,
sd1 = 1,
sd2 = 0.5,
n1 = 3,
n2 = 3
)
#> diff std_error t_statistic pval
#> 1 -5.5 0.6454972 -8.520563 0.003659956
