Please explain how to do this problem on paper and TI 84

Step 1

It is given that the confidence level is 0.90.

Here,

Step 2

The critical value using TI-84 is obtained as follows:

- Enter
**2nd > DISTR**. - Choose
**3: InvNorm(** - Enter
**area**as**1– 0.05**,**µ**as**0**and**σ**as**1**. - Select
**Paste**then click Enter**.**

Thus, the output obtained as **1.644853626**.

Hence, the value of z0.05 is **1.645**.

Here, the margin of error (*E*) is 0.10.

As there is no any estimates available, the ...
