... A firewood delivery company claims that on average one of their loads weighs 1 ton. Being sceptical of the amount of firewood received a customer arranged to weigh the next 10 loads delivered to households in his street. The sample mean was found to be 0.95 tons with a standard deviation of 0.09 ton ...

... estimate of the P-value – one that is close to but larger than the actual P-value. A conservative estimate of the P-value for the two-sample t test can be found by using the t curve with the degrees of freedom equal to the smaller of (n1 – 1) and (n2 – 1). If the null hypothesis is rejected using th ...
