IQs measured on a certain scale are normally distributed with a mean of 90 and a variance of 400. whats the probability that a random person will have an IQ between 120 and 130. the IQ of 51 people was taken, a sample mean of 90 and standard deviation of 64 was obtained. does this support that people tend to have IQs<100? use a 5% level of significance.

Mr. Karim is the owner of Philips home appliance. Recently Mr. Karim observed a differencein the taka amount of sales between the men and women he employed as sales associates. Asample of 40 days revealed the men sold a mean of Tk.1400 worth of appliance per day. For asample of 50 days, the women sold a mean of Tk1500 worth of appliance per day. Assumethe population standard deviation for men is Tk200 and for women Tk250. At the 0.05significance level, can Mr. Karim conclude that the mean amount sold per day is larger for thewomen?

A researcher wants to measure average cardiovascular health of university students and compare those scores to the average scores in the general population. Assuming that population variance is known, what statistical test is most appropriate for this study? independent-samples t-test single-sample t-test z-test for sample mean related-samples t-test
Determine your test statistic: either use a z-test or t-test• There are three key questions to ask: Is the variance of the population known? Is the distribution of the population normal (or approx. normal)? Is the sample size large?1. When the variance is known and either the distribution is normal or sample size is large,use a z-test statistic2. When the variance is unknown and a sample size less than 30, use a t-test statistic aslong as the population is normal (or approx. normal)?
