Hi there
Please help with this, it's for my assignment
The management team of a soccer stadium wants to estimate the average amount (in Rand) spent on snacks and cool drinks per spectator. It is known that the amount (in Rand) is normally distributed. A random sample of 40 spectators was selected and the sample mean is R37.93 and the sample standard deviation is R7.
Calculate a 95% confidence interval estimate of the actual average amount spent by a spectator and interpret the results.
2. The age of 10 randomly selected soccer supporters is given
below: 55 58 60 62 68 22 23 40 28 42
Given: s =17.13
Test at a 5% level of significance if the average age of a soccer supporter is
greater than 50.
Write down the null and alternative hypotheses.
Calculate the test statistic
Determine the rejection region.
Make a decision and draw a conclusion.
