Q19) the answer is 4 as 1 kg = 1000 and 1000 divided by 250 is 4
Q20) 3kg as 225 x 2 = 500 plus 800 x 3 = 2400 and 500 + 2400 = 2900 which is closer to 3000g which is 3kg

Given that <span>Sam
computed a 90% confidence interval for μ from a specific random sample
of size n. He claims that at the 90% confidence level, his confidence
interval contains μ.
</span>Yes, Sam’s claim is correct as a confidence interval has the meaning that a % likelihood exists
the population mean is within the interval.
There are 3 solutions I have came up with:
<span><span>1.</span></span><span><span> x = 1</span></span>
<span><span>2. </span><span> x = -1</span></span>
<span><span>3. </span><span> x = 8
