Let x be a random variable that represents hemoglobin count (hc) in grams per 100 milliliters of whole blood. then x has a distr
ibution that is approximately normal, with population mean of about 14 for healthy adult women. suppose that a female patient has taken 10 laboratory blood tests during the past year. the hc data sent to the patient's doctor are as follows. 15 18 16 20 15 12 15 18 15 11 (i) use a calculator with sample mean and standard deviation keys to find x and s.

<span>Answer:
Calculating the t test statistic
t = (xbar - mu)/(s/sqrt(n))
t = (4.40-4.66)/(0.28/sqrt(6))
t = -2.27452618972722
t = -2.275
The t test statistic is approximately -2.275</span>
