$\textbf{TI-84}$: Why do I get error data type with lists?

Question

In my $L1$ list, I have the values $\{0.3, 0.4, 0.5, 0.6\}$. I want to program my $L2$ list to calculate $Pr(X < x)$ for each value of $x$ in $L1$, using a normal distribution.

So this is what I'm doing: I go up and highlight $L2$, and then call $normalcdf$, with the lower bounds at $-10^{10}$, the upper bound at $L1$, $\mu = 0$, and $\sigma = 1$. When I click enter, I get Error: Data Type. I think it has to do with me typing in $L1$ for the upper bounds, but I'm not sure what I'm doing wrong.

Can someone please show me the proper way of doing this?

Any help is greatly appreciated.

Answer 1

Try putting this in for L2:

seq(normalcdf(-10^10, L1(X), 0, 1), X, 1, 4)

You can find the seq() function by going to 2nd-> LIST->OPS-> #5

seq() basically allows you to create a list ("sequence") of items by iterating an expression over the variable you pick (in the expression above, I used X). The above expression is basically saying apply the normalcdf() function to each item (1 thru 4) in L1 and put the results into a new list in order.
