Okay so here's the problem i'm having a problem with
A survey claims that 9 out of 10 doctors (i.e. 90%) recommend aspirin for their patients for
have children. A random sample of 100 doctors resulted in 83 who indicated that they
recommend aspirin. The observed test statistic in this problem is approximately
a. -1.33.
b. -2.33.
c. -3.33.
d. 1.33.
e. 2.33.
the observed test statistic is the Z value on the T-table that leads to a probability of 83/100 or .83 right?
so i just did invNorm(0.83) in my TI83 and i got .954, which is none of the answers. How am I thinking of this problem wrong / how can do i do it right?
