QUESTION 1.A zoo in New York claims the average weight of a newborn baby giraffe is at least 135 pounds. A zoologist decides to the test that claim by collecting data from a sample of 32 newborn giraffes and finds their mean to be 133 pounds with a standard deviation of 3.3 pounds. The claim was tested with a level of significance of 0.10. Answer the following: write Ho and Ha and identify which is the claim H0: µ≥135 Ha: µ&lt;135 The claim is the null hypotheses identify whether its left right or two tailed This is a right tail test. This is because the mean tested is at least 135. Therefore it means the claim is that mean is 135 and above. write the p-value The p-value will be calculated using the statistical calculator. However when doing manually it is given by (x-µ)/∂ to get the test statistic then finds its p-value. In The claim is the null hypotheses. identify whether its left right or two tailed This is a two tailed test. The mean can be either less or more than the mean. But its not equal to the mean. Write the p-value µ=11 x= 10.5 standard error is 2.3566/√8= 0.83318 Inserting the values in the calculator we get a p-value of 0.1271 Decide whether to reject or fail to reject the null hypothesis The p-value is greater than (0.01/2= 0.005). Therefore we do not reject the null hypotheses. Interpret the final decision in the context of the original claim. We therefore conclude that there is enough evidence to conclude the claim that the weight of the contents is 11 ounces.  NB: a larger p-value than the given critical p-value indicates there is high probability of making type I error. Therefore this gives us a ground to not reject the null hypotheses. [...]
